Whenever solving basic computer problems users should have knowledge of
some beep sounds as well as error message code, in our scenario single
beep sound is coming which is a good sign. Single beep sound is a
normal sound, computer make while startup, but screen is going blank
which is problem with monitor or power supply of the monitor or the
computer VGA cable having loose connection. Computer wiring need to
check and if any cable wire having problems then it must be replaced.
The second problem with this issue is VGA cable because of the loose
connection to monitor or cabinet. This VGA cable is fixed with screw
which need to check again if any loose connection or even the VGA
cable need a replacement .This basic problems need to understand if any
problem with computer, which can be troubleshoot if user understand the
problems. Power fluctuation is the common problem in electronic devices
which need to be taken care earlier in this case user can not took
care about the power problems.Computer required stabilized power supply
which increases the electronic devices life. The unstable power supply can
cause damages to the computer. The power fluctuation first victim is the
Computer power supply, which need to be replaced to start again the
computer if not big damage.Whenever high voltage fluctuation occurred that
time user has no idea of what happed all connections and power cable
working as it but it computer fails to start due to high voltage damage.
Due to fluctuation, computer parts have been damages and need
replacement.To replace power supply users, need to perform following steps,
• Open computer cabinet and check if wire burning smell is coming.
• Remove all connecting wires which are powered up motherboard.
• Remove the screws which holds the power supply in cabinet.
• Install new power supply in cabinet and fix all screw to cabinet.
• Connect all cables to computer parts.
Well, the 1st thing I would do is check the manufacturer warrenty to
find out if it's still under it's warranty, but if I wanted to take care
of this problem myself, I would start by unplugging the cord from the
back of the power supply, remove the case lid, and then I would write
down the brand and model number on the label on the power supply
so that I can order an identical replacement. I would try to order this
from a local computer shop, but if they didn't have an identical
replacement, I would just order from the manufacturer because you want
to make sure that it fits. Then before I start to disconnect all of my
power supply's leads, I would probably take pictures of exactly where I
need to reconnect each lead and to just help me to remember where
everything goes. Next, in high hopes that I can reach all of the power
connections without disassembling parts of the case, I would start with
removing the screws on the hard drive cage in order to remove the
hard drive cage to access the front panel power lead. Also I will be
documenting every step that I take so that I can perform the same
steps in reverse when putting in the new power supply. Specific screws
and parts need to be organized and kept together as well. You can
use a small piece of paper to label each group of parts to help
remember where they go. Once I've disconnected the leads, remove the
screws holding the power supply in place and carefully lift out the dead
power supply. Once this is complete, I would just place the new ps
in, following the instructions in reverse that I wrote down when taking
out the old ps. Then I would just check to make sure everything
works. I believe the first step you would have to do first is to check
the power outlet in the wall to make sure there is power still coming
from the wall. You can also plug in a power supply tester to read
how much power is running. After trying those choices, if those don't
work, then it means you would have to purchase a power supply from
your local store. If you end up having power supply coming from the
wall outlet then you need to access your computers motherboard and start
to work on fixing the issues coming from within your computer. Before
operating your motherboard, make sure you have the proper tools and
equipment required before touching any parts in your computer. Then you
can start to operate your computers motherboard and fix the necessary
problems in the computer. n case while turning on a system everything
is dead but the power to the system is working, the problem is power
fluctuation. Firstly, it is necessary to determine the wattage so that
adequate power supply can be bought. 80 plus rated power supply is
usually preferred. After conducting the thorough research, and purchasing a
new power supply, the system must be turned off and the power supply
must be unplugged. The power button must be pressed to get rid of
residual power. If the system has a modular power supply, you can
remove it and install a new power supply.
But if there is no modular power supply, the power cable to the CPU,
SATA drives, motherboard, and the GPU must be removed. The power
supply from the case must be unscrewed and the new power supply
must be installed. All the cables must be routed through the cable
management holes in the case and the power supply must be screwed
in the accurate orientation. It must be plugged into all the necessary
components like the CPU, SATA drives, motherboard, and the GPU. The
power must be tested to makes sure that the system can power on and
the side panel must be placed back on the case. First thing would be
to check to see if the device is still under a warranty. Then you
would want to check the surge protector to After that step, you would
unplug then power cord and then hit the power button on the PC to
ensure the power is drained from the machine. Next you would open
the case and check all the wires to ensure they are in good order
and replace as needed. If you have already selected a new power supply
and have it with you, you go through the process of installing it.
However if you do not, you would need to find one that could put
out the required power you need and you could also consider getting
one with more power output if you were considering upgrading your PC.
II may have to do a little bit more research on this question. So I’m
going try to answer the best way I can right now.I believe probably
the first thing is to unplug everything and check all the cables.Make
sure that none of the cables are damaged .Plug everything back in and
double check just to make sure. Especially the power cable,you don’t
want that being loose in the back.Second see if the flip power switch
is on the back of the computer.You might want to make sure that you
check the wall outlet as well. Sometimes wall outlets can be bad or
possibly have their own power switch or button.Now after you do all
of that and it still doesn’t work.You may have a number of problems
that could be wrong.It may not have enough wattage to run it. Getting
one of the monitors to run a wattage test.In my honest opinion because
I am an amateur .In my honest opinion, before I would decide to even
attempt to fix it. The fastest way is to see if you have a warranty
on a computer or laptop. Now if I don’t, I will have to do a little
bit more research on replacing the power source. About checking the
manufacture. Especially if I narrowed it down to what exactly the
problem is in general. It’s a classic IT story that almost sounds like a
joke, but it happened. A customer calls technical support because their
computer won’t turn on. After 20 minutes of troubleshooting, the
technician is becoming frustrated. Maybe it’s a bad power supply? The
technician asks the user to read some numbers off of the back of their
computer, and the user says, “Hold on, I need to get a flashlight. It’s
dark in here with the power out.” Keep safety precautions in mind as
you replace the power supply. Power supplies contain transformers and
capacitors that can discharge lethal amounts of current even when
disconnected from the wall outlet for long periods. They are not meant
to be serviced, especially by untrained personnel. Do not attempt to open
them or do any work on them. Simply replace and recycle them when
they go bad.Be aware that DC voltage is not safer than AC voltage,
despite its common use in batteries and lower-power components. Direct
current is more likely to cause a prolonged clamping of the muscles
than AC, which is more likely to fibrillate the heart, which results in
a deadly loss of coordination of the various cardiac muscles.Also, you
should be able to able to recommend specific products for power surges,
brownouts, and blackouts. These devices will help protect your power
supply and other internal components from an untimely death!
I think the easiest thing to do would be to first check the power
outlet in the wall to see if there is power still coming from that.
You could plug in something else or use a power supply tester that
you can get from a local hardware store. IF that isn't working then
you know that that's the problem and not your power supply. But if
there's power coming from the wall outlet then you need to access your
motherboard, which is your computer's main component area, and start to
diagnose the problem from the inside of the computer. Now I would
not recommend you access your motherboard unless you have the proper
tools which should be like the static pad static clip, things of that
nature to keep your computer from getting any unwanted electric currents
that can maybe possibly fry your motherboard or your components. Once
you make sure there are no loose wires or bad connections then you
should test your power supply and make sure it still functions properly.
If not then you buy and replace your power supply. I would first make
sure that its not an issue with the wall outlet or possibly even the
on/off switch being turned off. After ruling out all possibilities and
knowing that it is the power supply, i would look online for a
compatible power supply. I would make sure that i would be getting
enough wattage of a power supply, but not too much due to not
needing the extra wattage. After finding a nice, compatible power supply
with a similar wattage, i would purchase the power supply. When
replacing the power supply i would first unplug the system from the
wall and press the power button to let out all residual power, then i
would strap on my ESD wrist strap to the case of the computer after
lying it down. Next, i would remove the power cables that are currently
plugged into the motherboard. I would then unscrew the 4 screws holding
the power supply in place, and remove the old power supply. Putting
in the new power supply in the exact same place i would then screw
it in, plug in the 24-pin mother board cable, the 4-pin CPU cable, the
required 15-pin sata power cables and the 8-pin PCI-E power cable into
the graphics card. I would then plug it in and power it on. The steps
I would take is first check the outlet to make sure there is still power
getting to the outlet. With me being in construction I do have a voltage
meter that I can test the outlet to see if it is getting power. If the
outlet is getting power then I would check the on/off switch because I
have forgot to turn it on a few time before. Then I would check the
power cord itself and make sure it is plugged in all the way. Using
my voltage meter I would see if the PSU is getting power and if
that was getting power then I wold check all the power connectors
making sure they are all connected properly. If they are connected
properly and still not getting power then it could be a dead motherboard.
You have to check with the manufacturer to see if they could trouble
shoot the problem or they might have to send you a new one or you
might have to purchase a new one yourself. I would check that the
power cords are connected right and properly working. And if that is
not working I would then unplug power cords and begin to open the
computer to access the motherboard. Which is the principal components of
a computer. You'd need to make sure to already have the neccessary
tools you will need along with a storage tray for parts so that your
parts remain organized.Look at all your parts, to assure theirs no damage
and try not to. damage anything yourself. Then once and if you do
need a new part or parts, I would consider the price of fixing it
myself vs buying a new computer. And I wouldn't want to take on a
challenge to hard or spend more money on parts for the computer,
worth more then the computer alone. And even if you replace parts,
theirs still a chance ot might not be fixed. I'd rather buy a new
computer. Base on my research and little computer knowledge if you not
getting no power from a dead computer there could be any issues inside
the computer and will need fixing . There could be anything to make
the compute not working like for example a dead battery, loose cables,
burn cords , bad switch, power supply, bad power switch etc. But when
you have a situation where the computer not powering on and you
check your power outlet and nothing is wrong then the best thing to
do first is unplug all power cables before opening the computer and
also prepared yourself with the necessary tools like a pliers, black stick,
Philip head screwdriver, dental pick, blades, cotton swab and a tray for
storing the screws when repairing. When open the computer observer all
the parts look throughout everything to see any problems. You can check
the power supply by using a power supply tester and if it need a
new one then purchase one and replace the bad power supply. You
need to know you have enough power to run a computer. When find
the problems research and buy new parts try to buy parts that are
affordable and least expensive for you, you can shop around and compare
price for parts and then repair the problem. Well first you want to
rule out the basics, which is just checking the power cords. Just make
sure everything is plugged in properly. After checking the basics then
you get to the technical part which is checking the power that goes
to the motherboard. You will have to take your computer apart to check
the motherboard for any loose or faulty parts that may need replacing.
You must be careful when removing and replacing parts to ensure you
don't mess up other parts. Then put it back together and try trouble
shooting the system again. If you are still experiencing the same issue,
you may have to consider replacing the whole motherboard. Hopefully this
will get your computer up and running again. If after replacing the
motherboard and trouble shooting your computer still does not fix the
problem, you may have to consider replacing your whole computer. The
bright side of it is that you can maybe keep the old system for spare
parts should you run into this problem again with your new system, of
course after a little wear and tear. The quickest way to solve this
problem, assuming you really have gone through all the steps to insure
that there isn't a user or some simple fix. Which usually there will be
some other issue going on rather than the power supply actually failing.
According to toms hardware only about 10% of power supplies actually
fail do to some sort of bug. You would simply just need to find a
replacement power supply with sufficient wattage. Best buy has them and
a few other outlet stores do as well. Right now power supplies for
some reason are a hot commodity, maybe it has something to do with
so many people staying home and building pc's. What you are really
gonna want to take in consideration though is why your PSU has failed
in the first place. You're going to want to check for some sort of
electrical interference, house dusts clogging the fan, making sure the power
supply is getting enough ventilation but also age could be possibility as
well. So assuming that my power supply has gone bad, the first thing
we need to do i s get some tools (Phillips screw driver) and safety
equipment like gloves if you desire. Make sure you have purchased the
correct replacement power supply for your computer. Obviously unplug
power cord from the wall and then continue to remove the screws to
the panel to get to the back. Disconnect any cords leading from the
power supply to any different components of the computer, in doing so
you can have an easier time removing the power supply when it comes
time to do so. An important step is unplugging to 8 pin CPU power
connector and of course the 24 pin to the motherboard as well.
Removing cables carefully and avoid tangling. After ensuring all cables
are disconnected you have to remove all the screws holding down the
power supply down to the computer. Not sure how many screws are
holding down the power supply, it all depends on the vendor. Replace
the new power supply and try to follow your steps backwards as best
as you can. I would check all power connections such as ww the power
cable, is it plugged into the wall and the other end into your power
supply? Be sure to check every possible issue , try to trouble shoot
on a diffrnt computer if needed w If you are getting power to your
motherboard, the next thing to check is that your front-panel button is
connected properly. It’s different for every case. If all fails it’s time to
replace I focused most on the power something is misfiring make sure
the CPU’s are working . the quickest way is to unplug everything. You
should first determine what wattage the power supply is, so you can
buy an adequate power supply, preferably a 80 plus rated power supply.
After researching and purchasing a new power supply with all the
prerequisites, you must turn off the system, unplug the power supply
from the wall, and then press the power button again to get rid of
the residual power in the system. If your current system has a modular
power supply, and you also bought a new modular power supply, you
can simply remove the power supply in the system after unscrewing it,
and install the new power supply by plugging in the modular cables.
However, if you do not have a modular power supply, or if you did
not purchase a new modular power supply, you must remove the power
cables to all SATA drives, CPU, motherboard, and the GPU. Following
that, you must unscrew the power supply from the case, and remove it
and all the cables attached to it. Install your new power supply and
route all the cables through any cable management holes in your case
to make life easier, and screw the power supply in the correct
orientation and plug your power cables into all SATA drives, motherboard,
CPU, and GPU, and quickly test to see if your system powers on. If
it does, then put the side panel back on the case and then you will
have successfully replaced a bad power supply. The first step would to
determine what wattage I will need to install into the system. Either try
to calculate what would be needed for the system taking in consideration
of components like the motherboard, RAM, video cards and hard drives,
or it may just be easier to take a look at the old one when it’s
removed to see what the watt output is. This is to make sure the
system has adequate power to run properly. While replacing the power
unit you want to disconnect the computer from the wall, start to
dismantle the side of the computer and obtain an ESD strap to not
damage any components with electro static discharge. While using the strap
disconnect the power supply cords and remove all necessary hardware.
Further removal of other parts may be needed such as video cards to
allow access to the power supply. Replace the unit and reassemble the
removed parts and close the computer side panel. After all of it is put
together plug the computer into the outlet and try powering on. I
think everyone that has replied is making the removal and replacement
of the power supply unit more than what it should be. The fastest way
is to power the system off and start unplugging the machine. CPU and
motherboard connectors are the main ones. If you have a dedicated GPU,
SATA powered devices would be next. Once you have disconnected the
cables from the system and you remove it, simply plug everything back
in with the PSU outside the case. The reason is to make sure that
the PSU is properly working. If it does not boot it could be a PSU
issue that can be correct or something else but if it’s the PSU, then
it can easily be found. When the system boots and you leave it on
for a few minutes, you can then power it off and start doing cable
management. Once the cables are managed, you close the computer up
and go about your day. Question to all: How does one prevent ESD
when you do not have an ESD bracelet? Other than replacing a failed
power supply, you may also use these steps when upgrading your power
supply if your upgrading a graphics card or a component that will
require more power. These instructions will be on a PC in a tower
case. First ensure the computer is unplugged from the wall outlet for
safety. Turn the case to its side and remove the side panel, in this
case I had to unscrew two screws to remove the side panel from the
case. One thing to consider there could be a case fan installed and
you may have to unplug it before you can fully remove the side panel.
With the side panel removed, your power supply will be either on the
top left or bottom left depending on the case. Now it is time to
begin removing cables from the old power supply. First start with the
cable going from the power supply to the optical drive, next unplug the
cable from your hard drive, once those are unplugged you will have a
better view to see what else needs to be unplugged. In my case a
fan cable, and two cables going to the motherboard. With the cables all
removed its time to take out the old power supply. Turn your case so
the rear is facing you, and you will be able to see the screws that
need to be removed in order to remove the power supply from the
case. Make sure you put the screws in a spot where you won’t lose
them, you will need them again when securing the new power supply.
Now you can turn your case back to its side and remove the old
power supply. You can now install your new power supply into the
case, and plug all your cables back to where they go with the supplied
cables your new power supply came with. Start with your motherboard,
then graphics card, then move onto the HD, and finally your optical
drive. Once everything is installed and plugged in, try to power on your
PC. If everything was installed correctly your PC will boot and you can
put the side cover back on the case so you can enjoy your PC again.
The quickest and easiest way to solve a bad power supply problem is
just to replace it and forgetting about repairs. Before doing anything you
should buy a new power supply. The first step would be to turn off
the PC, unplug it, hit the power button again, and then remove the
computer’s case. It should be located in a corner of the computer’s
case. The second step would be to make sure the new power supply
is compatible with the case, PC, and motherboard. This includes making
sure the power supply cables can fit correctly. The third step would be
to unplug the power supply cables from the motherboard. The fourth step
is to unplug the power supply cables from the hard drives and the
CD/DVD burners. The remaining steps would be:
• Remove the screws that holding the power supply in place.
• Take out the power supply.
• Plug in the new power supply into the wall before installing it.
• Make sure that the power supply’s voltage is correctly set.
• Install the new power supply, tighten screws, and reconnect the
cables.
• Plug the computer back in.
• Turn the computer on to see if it works.
• Turn off the computer and put the case back on.
Through the research I have done on power supplies and how to replace
them, I have come to the conclusion that though it may seem like a
daunting task, I read that it is fairly easy to replace if all the steps
are done correctly and no corners are cut. The first important step I
believe in the process of purchasing a new power supply would first
get to know the previous power supply that is being replaced. When I
first read that I thought why I would get familiar with a part that I
am potentially replacing anyway. After reading more into the step, I
found out the importance of making sure you match the previous power
supply with the new power supply because if you purchase a new power
supply and it may be slightly larger leaving the possibility that your
brand new supply may not even fit in the case causing you to
potentially buying another power supply that will fit the case. Of course,
we must abide by the ESD procedures when replacing the power supply
because if that is not taken seriously you can do more potential damage
to your computer than helping it. Once the power supply is installed, I
strongly suggest making sure all connections are secured properly before
placing the lid back on the case. Before doing anything I believe the
first step would be to start doing some research and look for a
replacement part. I need to be sure that the replacement would be
compatible with my other components. To ensure the new part would be
compatible, I would need to add up the total wattage needed of all
the components and then add thirty percent so that every part will get
to the power needed. I would also need to make sure that the new
power supply will fit inside the case. Next, since the computer isn't on
to begin with, I wouldn't need to power it down, however, it's still
important to unplug it and hold the power button down to ensure there
isn't any residual power still in it. Before doing anything else I'd keep
a cup handy to prevent losing any screws and keep a list of anything
I unplug or remove as not to forget where everything goes and make
more problems for myself later. After opening the case and attaching the
ground bracelet I would try and find some way of backing up my
data, whether through downloading it to another computer or copying it
to another hard drive somehow, just to be safe if anything did go
wrong. Afterward, I would unscrew the power supply from the case,
unplug it from everything while keeping a detailed list of what's
happening, take it out, and then screw the new power supply to the
case. After plugging everything back into place I would power the system
on and make sure everything is working as intended and then close the
case if everything went as planned. Power supplies are rated in watts.
A watt is a unit of power. The higher the number, the more power
your computer can draw from the power supply. Think of this rating as
the “capacity” of the device to supply power. Most computers require
power supplies in the 250- to 500- watt range. Higher wattage power
supplies might be required for more advanced systems that employ power-
hungry graphics technologies or multiple disk drives, for instance. It is
important to consider the draw that the various components and
subcomponents of your computer place on the power supply before
choosing one or its replacement. First I would do some research and
investigate for the correct power supply for the unit. I would determine
if I could increase watts for more power, or just replace the power
supply with the original part. I would turn off the tower and power
down the unit. I would then disconnect the power cord from the wall
outlet. Next, I would make sure the unit is off, and discharge all
residual power by holding down on the power button again for a few
seconds. I would read the user manual to see the easiest way to
remove the power supply. Next I would disassemble the case to the
desktop and attach my static band. Then, I would label and remove all
the power cords attached to the power supply. After that, I would begin
removing the screws and placing them in a bag or cup so I can find
them later. After removing the new power supply from the packaging I
would make sure it is the same or equivalent. FInally, I would begin
the installation process and begin screwing the new power supply back
into the unit. Next I would begin re attaching the power cords back
to the power supply. Before adding the cover back to the desk top I
would check and make sure all abnormalities were removed from the
case, then I would test for proper power consumption, once that has
been determined, then I would power down the system once more and
reattach the cover and power back on one more time and reboot the
system then run the BIOS system check and installations. ww
