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 the power cable, is it q 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 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. qq
