PCCHIPS M848A V5.0 problem

[T. T.]

Dear all:

My old Epox 8RGA+ motherboard was dead (bad cap problem), so I bought a
cheap PCCHIPS M848A motherboard (V5.0) in the hope to replace it. After
I installed it and turn the power on, first the CPU fan would start
spinning, but then after like 5 seconds, the power will automatically
turned off for some reason. Does anyone know what might be the issue? I
heard that this motherboard is very picky about memory, the memory that
I'm using is Corsair CMX512-3500C2PT XMS3500 (which is probably PC-3500
I believe, rated at 433Mhz CL2). Does anyone know whether it is the
memory problem? If so, what are the memory that are tested to be
compatible with this motherboard (V5.0)?? Thanks!

Have you got the CPU fan plugged into the right header on the mobo?

yes I think so, that's why the CPU fan would start spinning for 5
seconds.
However, I did notice that the heatsink compound between the heatsink
and the CPU were almost gone, should I re-apply some new compound??
Thanks!

Yes, it could well be deciding that the cpu is getting too hot and is shutting down.

I asked 5 secs is as long as some boards spin up for if the CPU fan is in
the wrong header. But if you suspect you dont have sufficient thermal
compound, then yes, clean off whaever remains with some rubbing alcohol and
apply some new stuff.
