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 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 oo 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. oo
