hangup then reboot

hi there
wanted to share my problems with you, and see if maybe you can provide some help:)
just changed my motherboard, cpu, memory, power supply and video card (i kept the case and hard drive)

im running windows 7 final version and the system crashes like once a day, usually when im playing but i've seen it crash while watching a video (its rare)
ive got the most recent drivers, installed everything for the motherboard that i could find on the website or windows update. Tried lots of bios settings, no luck

any ideas?

ps) no overclocking done on anything; and voltage seems correct when i look into amd overdrive

Looks like hardware is causing the issue.
