With reference to my original thread here http://forums.hexus.net/help-technic...else-help.html it would seem I've ran out of ideas.

I tested all 4 sticks of RAM for 9hrs with memtest, 2 errors reported.
I used one stick of RAM and got the usual shutdowns, about 5-10 shutdowns in as many minutes, then managed to get it to stay stable for another night of memtest, NO errors. I'm guessing the problem isn't ram after all, seeing as I've tried nearly all modules and still the problem.

So, onto what I should do next...

I have no idea which part could be causing the problem, the ram, the psu, the mobo, the cpu, I just have no idea. As the problem is sporadic, ie. Stable for many hours then 20mins of regular shutdowns, I don't want to RMA some parts only for the retailer to find no fault and charge me accordingly. I guess I could RMA the corsair ram, but all other parts are bought from Scan and I believe they charge...

Any suggestions?
