It starts to turn on but only for about a half a second. It doesn't appear to be hard-drive or software related.. I'm thinking the power switch.. any suggestions? I can't get parts up here, does anyone know how to hot wire a computer?

I tried hot wiring it.. it does the same thing.. It tries to turn on, sometimes it even tries to boot, but then shuts right down. The fans turn on for a second or two until it shuts down. The computer had been pretty dusty but we cleaned it a couple weeks ago when we started having problems with it shutting down in the middle of a session. It has been getting progressively worse ... shutting off more often, etc.. and now this... is there a particular sensor or something I can check for dust? any more suggestions?

Sounds like the power supply and sorry you can bypass it but it can damage your other computer parts beyond repair. But if it is the power switch the computer should boot by holding the switch in. if it does take the cover off your computer and with your computer UNPLUGGED cut and connect the power switch wires together bypassing the switch then start again good luck :)

OK first thing it is NOT your power switch because if it was, it would not even turn on. Second, if it wont turn on theres not reason to "HOT wire" a computer because it isnt on. Now Hp desktops preform in this behaveior if, some problem is detected in the motherboard to help protect it from damage. This is usually caused by the something being wrong with the power supply. Now, honestly i really cant help you at all with fixing this computer because I would have to be at the computer to fix it. A solution you could to is taking the computer to the store and having them fix it. But be warned, if it is the power supply, theyll probably make something up and charge you way more than it really cost them to fix it. So i dont really have any GOOD solution for you, because thier isnt one.

*IF* you don't have access to another power supply...
NOTE: ALWAYS TURN COMPUTER OFF BEFORE Removing\Unplugging or Plugging back in.!!!
1: REMOVE EVERY card you can in the computer. (EXCEPT VIDEO CARD)
2: UNPLUG EVERY DRIVE..
*IF* computer starts, you know at least ONE of the things you Removed\Unplugged is bad. *IF* the computer starts to boot up it should say something like "Boot system not found, insert boot disk"
So start by connecting the C: hard drrive back and see if the computer starts. *IF* it does, then try connecting one thing back in and try to restart computer UNTIL it STOPS starting up. That will be your bad item.
*IF* it still doesn't start after removing and unplugging there are still 4 things that could be bad.
1: The video card is bad.
2: The power supply is indeed bad
3: Circuitry on your motherboard is bad
4: Both power supply & motherboard are bad.
Only thing left to try then is another power supply that is KNOWN to be GOOD. *IF* a KNOWN GOOD POWER SUPPLY DOESN"T fix the problem you have a BAD Motherboard.
