It is all explained in my guide, it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!! It could be the power supply or a short circuit, but may also be a loose connection or dead mainboard. However you must diagnose the fault before you purchase replacement components, other wise it could cost you lots.

Thanks

Computer wont turn on


Make sure the tower is getting power. There will be a green light on the back of the tower where the power cord goes. Make sure the cord is snug and that it is securely plugged in to your power source - I'm hoping it is a power surge strip and in which case, make sure the surge strip didn't get unplugged or turned off. If you have it plugged directly in to the wall then make sure that outlet has power by plugging something else in to it that you know works. After doing all of this, make check to see if there is a light on the back of your pc. If not, unplug the power from the back of the tower, wait 30 seconds at least, and then plug it back in. Hit the power button on the front just once, if it doesn't power up, press and hold the button in for a 2 seconds and release. If that doesn't work, your power supply may have gone bad. That happens from time to time. Good luck, hope this helps!

Sounds like a dumb question, but I was moving my comp to lean over and change a printer cord and the comp shut off. I have checked all the power cords etc, but when i press the on button the comp does not...


There is usually a reset and a ON button. the latter being larger was that one tried?
If you have a battery UPS you might have turned that off and it will only supply battery power might not be enough to turn unit back on.

Nothing happens when push start button. power cord etc good ??? is this a power unit failure?


make sure the outlet is recieving power

unplug the tower from the outlet & then replug it in & see what happens

make sure all cords are plugged in correctly in the back of the tower

then if nothing happens after you push the start button, power supply & cord could be bad

the same thing happened to my daughter's pc & had to replace power supply & shorted out the motherboard

HP Tower (2000 Media Edition)


Sounds like your power supply unit is dead. Do you get any power or hard drive lights on the unit? If not, I'm afraid it's a repair shop problem.

Sorry to be the bearer of bad news!

Tower gets no power


90% of the time this symptom indicates a bad power supply.
If a generic system and in some name brand systems, the part is quite cheap (about $40) + labor.

In rare cases, the power switch could be bad.

do you still have your restore CD? try to fresh restore it and updates everything on that unit again. Often online gamers send you malicious script that crashes your system.
