|If your temperatures are high in BIOS then you probably have a system that is clogged up with dust build up. Open the side (off and unplugged) and blow out the dust, especially from all heat sinks, fans, and vents with a can of compressed air (Dust Off or similar) from a computer or office supply store.|
If your temperatures are normal, retest your memory using a Memtest86 on a bootable CD. Any errors are a problem. If it finds errors or shuts down again, retry with one stick of memory at a time to find the possible bad one and prove that other components are good. If you find that one or more sticks are good, try Windows with one stick, it should work, though slower than normal. Replace as needed. It is recommended to replace memory as matched pairs for best performance.

You have to be a little bit crazy to keep you from going insane.
