I am posting this here because I cannot for the life of me narrow down an issue I'm having with a rig I have in my possession. Basically, I have a system that will shutdown on it's own without warning. Sometimes it will display Vista's shutting down message, other times it will just cut the power.
The first thing I suspected was the power supply - so I tested it with both a multimeter and a glorified power supply tester I had ordered for my emergency repair bag... both showed the power supply was fine (not under load) but I swapped two different power supplies in place (that are from working systems) and the issue still occurs.
I then suspected possible heat issues... but the processor is running cool to the touch (heatsink) and monitors show ~34c/46c idle/load. Reported in Speedfan and CoreTemp.
I've also tried reseating ram and booting with single stick/etc and same thing happens.
So the point I'm at... well, I've no clue as to what is causing the random shutdowns. Any thoughts/suggestions?
