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 ss 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 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. ss
