Hey guys, I have an issue with my MBP where it will lock up after around 25-45 minutes of use - the mouse is still able to move and if i have music playing it will continue playing for a while before finally crashing. At first I thought it was definitely heat but even with fans set at full speed and a fresh thermal paste application the symptoms are still EXACTLY the same in both osx AND bootcamp win7. Does this definitely indicate that this is a hardware problem - reformatting etc wouldn't fix it? I always thought osx / bootcamp were completely unlinked since you have to reboot to switch - but I could be wrong on their relationship. Since the symptoms are exactly the same I was thinking it was a hardware problem - but I'm running out of ways to try and fix it w/o buying a new logic board. Could this be a software problem?
