Question about Compaq Presario 5000 PC Desktop
My hp pc was working fine. then suddenly power went out. now i can't turn the power back on. i push on the power switch. but nothing happens. what could be the problem? if i switch the power switch. would that solve the problem?
Unfortunately, your Power Supply Unit (PSU) is probably dead. When the power comes back on, it is often accompanied by a power surge. This can quite often destroy your power supply. To replace this, unless you have experience doing so, I would suggest taking it into a PC repair centre, as power supply are serious business, and installing one incorrectly, or installing an incorrect unit, can cause further damage to the computer.

It does sound like the power supply. Try flipping the power swich in the back, by the cord, then press the power button on the front again. But most likely, the power supply will need to be replace. If you do happen to get it come back on, take the cover off and verify the CPU fan is spinning, if it's not, that could be the problem as well.

it could be a faulty switch or the bad lead connections
test all power and data leads that attach to your hard drive IDE SATA
MOTHERBOARD TO THE HARD DRIVE make sure they have secure dust free connections and are not faulty if its a flat ribbon 40pin ide
this will be the first to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure dust free connections
a computer needs power and data to travel through every working device and continue its cycle and have a finishing point so any faulty leads will end up with a computer error
make sure the CPU has a secure dust free seating with thermal paste
make sure your ram modules are securely seated with no dust in the sockets also the Cmos battery has charge with no dust in the socket
on some motherboards cmos batteries are soldered in
hope this helps
