motherboard power up 2 seconds then shut down immediately

[T. T.]

Hi all:
I'm having this problem on my newly purchased PCCHIPS motherboard m848a
v5.0. I emailed the PCCHIPS and they replied that it could be the CPU
heatsink that is NOT secured and did not has themal compound between it
and the CPU, and this could cause the issue that I'm having. I did
notice that the old themal compound had become "solid" and probably no
longer is good, but just wondering, could this cause permanent damage
to my CPU?? Thanks!

Yes, its possible, but the shutdown may have protected it.

It could also be that the fan speed sensor on the CPU fan is bust and
therefore the BIOS thinks the fan isn't going round and cuts off the power
to protect the CPU.
You have got the CPU fan plugged into the correct header on the mobo I
presume?

Not having good thermal compound between the CPU heatsink and the CPU would
cause the CPU to overheat and self-destruct.

Yes, it is a hard lesson to learn, after building systems for so many
years (over 10+ years I guess), I just found that I killed that CPU
because I didn't put new cooling compound between the CPU and the
heatsink! Duh!

What happened was that I (accidentally) put the fan speed sensor into
the wrong header, and the first time it booted happily, only that the
CPU really got overheated and I didn't know that. Then the 2nd time I
did that, and as I didn't put in new cooling compound so I guess the
CPU got overheated the 2nd time it booted, and just burnt to dead.. I
opened up the CPU and found that it burned almost a hole on the CPU (oh
boy it was quite a sight!), so apparently the CPU is dead.

Now I'm wondering could this also killed the motherboard at the same
time by any chance?? I don't have an extra socket-A cpu at hand to test
it, any possibility that I also killed the motherboard?? Thanks!

I've reported you to the RSPCPPCPUBCFC, you'll be sorree...
