My computer powers on, but singal to monitor, no beeps, or lights. The CPU fan keeps running at high speed, and it's very noisy. CPU is generating no heat. I have tried unpluging everything to the machine and holding down the power button for 30 seconds. Checked the ram and removed one of the sticks, took out the battery and then back in again, and I checked for dust but everything seems very clean. Still nothing.

Hi

have you located cmos reset jumper (if you removed battery you may need to wait a long time to discharge capacitor)

have you checked voltages 5V & 12V on a spare molex connector black = 0 = ground, yellow = 12V red = 5V

On Intel CPU ATX 12 V to motherboard is critical to start up

Have you checked capacitors near to CPU (part of regulator circuit) for bulges or leaking ?
(bad capacitors needs expert to replace or new motherboard)

regards
