Computer shuts down

PrepareU

Lately, i have had some times, that when i joined a game or waited on the scores at the end, that my whole computers shuts down and restarts itself..
and i seem to only have this problem while playing cf..

anyone knows where this problem may come from?
cuz i don't know aanything about comps xD
(tried redownloading cf and did some full virus scans, but those things didn't help)

Xpl0zi0n

ur not the only one..
