Win 7 64bit freezing up

alright, im home from work. going to try this for a couple more hours to be sure it wont freeze. then if it doesnt freeze time to figure out which services is causing it.

well, it froze last nights 3 and a half hours were just luck i guess

i have had a box fan on it for the past 3 days to be sure

eh, i have no idea what to do. im so tired of trying to fix this

i will but not right this second, i am waiting for it to freeze again so i can try the thing the guy posted yesterday. and i built my computer so no model

ok, it froze i tried what he said it did nothing at all, i started it back up and did not hear any beeps.

not trying to hijack, but i am having the same issue. but mine only stays up for about 20 seconds. stays up in safe mode forever.

i am using ultimate trouble shooter, everything is turned off in start up as well. have run all the malware software plus external scans through norton. im clean. so think that it is a software issue. can have system off for days, turn on then crash. not a heat issue.

help
