 |
|
I have a dual-cpu motherboard (intel l440gx) with two pentium 3 cpu.
Due to my stupidity, I burned both CPUs and I'm pretty sure they're
totally dead.
However, I'm not sure if the motherboard is still good.
When I put the dead CPU in, the cpu fan still runs, the on-board
network card still blinks, the hard drives still spins, the cd-rom
still responds.
But there is no video and the floppy drive doesn't blink.
If I pull the CPU out or memory out, it will beep 4 times.
There is no burned chips visible on the motherboard.
I performed a CMOS clear but the result is still the same.
So is the motherboard still good? I don't have two good CPU to give
it a try. |

There is no way to know for sure without putting in at least one known good
cpu but it sounds promising. It's a long shot but maybe you could try
underclocking one of your "bad" chips on the off chance that it'll work at a
lower speed? Be aware that there is always a chance that if the MB really
is bad it'll kill a new cpu as well.
