Hopefully Finally the end of a 5 month battle with my PC is coming to a close.... Okay heres what the problem is. As some of you know (from previous posts here) I have been having problems with my PC since around July. I didn't install any new software/hardware...nothing. Yet I got BSOD's...and more BSOD's...Along with the BSOD's all my games became unstable. To this very moment I can play CSS for about 1hr before it crashes. Rise of Nations, crash along with world of warcraft, Call of duty, Warcraft 3, Fahrenheit, Black and White 2 everything! Although they crash after different lengths of playing they will all crash with this 0xC0000005 error. Now at first I thought it to be RAM...I did memtest/windows diagnostics and 10 others. All came back with 100%. Did burn in tests as well. All 100%. then I came across this marvelous program named S&M.... Well Ran S&M and on CPU test it passed it on both caches and on the integer. Got to CPU (FPU) test and after about 1min, BOOM! BSOD!...So XP rebooted and i decided to run the RAM test on S&M only...100% no problems! Ran the CPU test again and at the exact same place it crashed! With a different BSOD. I'll post the 2 dumps here and if you want more i have no doubt i can get S&M to make some more Before people accuse my RAM I will like you to all know that it's 100% tested fine AND I used my brothers PC's RAM in here which I know is fine and yet games did the exact same crashes. As for CPU temp during S&M...Well I wouldn't call 41 degrees overheating now :/ As for cleanliness of case: Gave this PC a full cleanage over the weekend making it look brand new ^_^ Thanks for any confirmation you guys can give me EDIT: Hehey!! Well another forum just recommended I use Prime95 if I think the culprit is my CPU so I did and what happened...Crashy! BSOD with the exact same STOP error! The final CPU temp at time of crash was 43 degrees.
