|Hope I can get this typed before it happens again. Just built a new desktop PC. Have been building them for about 8 years. Probably built 30-40 of them. It will reboot when under a load. (running multiple programs at once. No gaming just surfing, listing to music. Nothing heavy. Bought all parts from Newegg except ram which came from local Intrex computers. At first I thought it was the motherboard so I returned it to Newegg and got a different brand. I thought that fixed the problem because I was able to get OS loaded, but then it started again. At first I thought it might be a temp. problem (8 core processor) re-seated heatsink, left cover off turned up fans to max. Watching temps in sidebar program and max is only 32C under full load.|

Problem: Reboots when cpu is put under slightest load or when running cpu calculation test. Does fine when running Stability or FPU test.
Sometimes it just freezes and the screen becomes fuzzy with red, blue & yellow lines.
While ideling cpu is at 1% usuage and memory usage is at 31%. Temp. 19C under load it gets up to max 32C.
Motherboard bios has been updated to latest 2-8-12
Tried changing almost every setting in bios with no change. Currently in default setting.
Windows will boot fine and you can surf and maybe play music but that is all. Anything else will cause reboot.
