I just built a new computer. I downloaded the iso for windows 7 from digital river and burned it on DVD. I set the computer to boot from CD and then it says "Windows loading files" and then my computer shuts down right after the bar finishes loading..
double checked on the wires and changed the optical drives wire to a different one. then I ran Windows Memory Diagnostics Tool and it died @20%.. I checked the CPU temp and its 85c, everything else below 50c.. is 85c too hot? I'm not sure if it might be related to the CPU cooler, but it seems to be mounted with the thermal glue and the pull-push fans + radiator on top are working well.
How did you check the CPU temperature? The BIOS can sometimes get it wrong if it's not properly set up for your CPU. Try CoreTemp or RealTemp; if they give the same readings then you have a problem. I would say that anything over about 60 under load, or 40 when idling, is getting too high. I would expect lower temperatures than these in practice.
Overheating would certailnly explain your symptoms, particularly as they happen at the "expanding files" stage, when you would expect the CPU to be working a little harder.
I figured out the problem. The CPU cooler's fan wasn't plugged properly into the CPU Fan Header in the mobo, so it wasn't even functioning. I guess it kept shutting down to protect the chip. I wonder if my CPU is damaged though >_>
