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 a the power cable, is it a 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. a 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. a
