When I try to turn on my PC I get a blank screen, no beeps, the fans are running and the lights on the motherboard and power supply are on. When I try to turn the computer off it will not shut down, the light on the power switch stays on. I disconnected it from the power surge, then reconnected and I did not have to hit the power switch it was already on. Please help. Thanks
It was the RAM, I took it out and put it back in and it booted right up. The reason I didn't think it was RAM was because I had no beeps.But thanks to all of you who helped!

What was already on?

Press and hold the power button for 8-10 seconds. Does it turn off? When it is on, can you hear the hard drive spinning? Do you get a POST screen. May be a possible bad power supply, even though the lights are on remember it only takes 0.7volts to light up an LED. Do you have access to and know how to use a multimeter? Check the output voltage of the supply. If not try things like opening up the CD drive does that work?
Did you recently add anything to the PC?

No I didn't add anything to the PC, one day it was working fine and the next it would not boot. I thought it may be the video card so I took it out and tested it in another PC and it worked. I'm thinking it may be the AGP slot or the mother board. Any thoughts on that? I'm almost positive it isn't the power supply because the CD drive opens and the fans are running.

did not kill the power supply,but has probably corrupted it, will mean that incorrect volages are begin supplied, whilst the CD and led's are OK the voltage required by the MB critical, if it's not in the correct range the MB won't work, by continuing to run incorrect voltages it will die.

Somethings come to mind:

1) Memory. If possible take out and replace
(re-install)
2) Graphic card. If possible take out and
replace (re-install).
After this re-boot and see if your computer starts ok.

Please post back if you have anymore problems or questions.
