hm i cleaned my cpu cooler (it did not have that much dust in it,i tend to clean my pc 2x a year)...the thermal paste is wore out at 1 spot,and i believe that is the cause...anyways i found some paste at home,applied it,cleaned that little dust i had and the game now works,,2 hours stable gameplay...and prime95 handled it ok
i guess its just one of those things,my processor is about 3 years old,i basically never shut down my pc because im always seeding something or downloading overnight. the paste wore out
anyways thank you all for pointing to me that this is a processor issue and it is a heat issue after all
may this thread shed some light on other unfortunate users that encounter this same problem
