Having a bit of an issue here. Basically I just built a new PC with the following components:
Before purchasing, I checked all CPU, motherboard, and memory specs to make sure that all items were compatible. My issue is that the machine randomly shuts off -- no BSOD, just powers off. There is no single activity or time interval that triggers it -- it simply shuts off at random. I have performed the following tests in order to mitigate the issue:
- tested the power supply and it checks out
- performed several clean installs
- run memory tests, "burn in" tests, etc using UBCD 5.03 and everything seems to check out.
However, these random crashes continue, and are quite frustrating. Interestingly, if I do absolutely nothing (i.e. leave it running overnight without touching it) it continues to run with no issue. If anyone has any suggestions about what path to take next as far as diagnostics, I'm all ears. Otherwise it looks like RMA time.
EDIT: One thing I forgot to mention is the fact that the PC won't power back on unless I first switch off the power supply for about 30 seconds. I'm not sure if this is due to the manner in which Windows randomly shuts down, or due to a fault that is wholly that of the power supply. Thoughts?

Do you get a minidump that can be analyzed? Being able to figure out if there is a faulting module, consistently, would go miles for figuring out what it is. – vcsjones – 2011-03-07T02:14:10.447
Have you checked out the HDD or processor temperatures? It is possible that something is getting overheated, prompting the shutdown. – MaQleod – 2011-03-07T02:55:02.907
No, no chance for a minidump -- it simply powers off. As for temps, I've tested and checked everything. Unless something is being misreported all temps are well within acceptable limits. – humble_coder – 2011-03-07T03:18:39.680
This may sound silly, but it happened to me. One of the cables going to my motherboard kept falling and getting caught in a fan which would stop turning and the whole thing would shutoff. – a sandwhich – 2011-03-07T05:57:43.803
I was wondering if you ever figured this out, I have a notebook exhibiting similar symptoms except I can boot to Windows or Linux normally but if I put it in safe mode to run a virus scan with minimal software running or try running diags off of UBCD the system will randomly shut down, at times when it does it with safe mode it acts like it is overheating though it isn't. – RadG – 2011-08-25T12:18:55.377
