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 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. b
