I have my old system working fine until recently.

It has AOPEN AP53 motherboard with P133 MHz with Award BIOS.
(This is supposed to be my backup system.)

It lock up when BIOS POST starts. Right after it displays AWARD MANU. INFO.

Sometime it will boot, but most time it locks up. I tried to disconnect everything except CPU, all Case connector, Memory, Video Card.

I get no beeps.

I replaced motherboard with known good motherboard. Still same problem.

What could be wrong. There are three choices : Memory, Video or CPU.
And I know i have correct CPU jumpers.

Thanks.

Right off hand I would guess that if it suddenly started with no changes to the system that you have a heat or power supply problem.
