A friend gave me this, so I have no idea what the specs are. Basicly it didn't have a harddrive, so I figured this was the reason it wouldn't power up, I got a new one and I am still having the same problem. I press the power button and the processor kicks on, followed by the harddrive and the CD drive, then it just shuts off. I never get a display or anything. One of the ram modules had a loose heat spreader, so I removed it and still no go. I cant find a Cmos to reset, so I am kinda stumped. Does anyone know what could be wrong? I think it's a pentium 3 800MHZ, I know it has the radeon mobility chip.
