Computer Won't Start!
I've been resurrecting an old computer of mine for a mate, and it's suddenly decided to refuse to power up. It had been working perfectly, though the CPU fan was a little noisy. I had to change the CD drive, and when the machine was back together it got as far as the POST single beep (normal), then powered down. I suspected the power supply, and changed it for a known good one - same thing. There's no response to either the power or reset buttons; the machine attempts to power up on its own once the mains lead is connected and the power supply master switch is selected on. Once it's powered down, it will not power back up again at all unless the mains lead is removed for a few minutes. The CPU fan is working.
Any thoughts, chaps?
The tech stuff: it's a Pentium ll 333Mhz (slot 1) processor, QDI Legend V mobo, 128mb SDRAM, Matrox G100 graphics, AWE32 Soundblaster, Motorola V90 modem, Toshiba 32x CD, Zip 100 internal, 4Gb and 2Gb HDDs, Win98SE OS. As I said, old! (But all in good nick, and not heavily used).
