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 yy 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. yy 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. yy
