For the past four weeks I've been having blue screens of death pop up. At first it was only happening while running games. After reinstalling graphics drivers and testing other fixes a few times (and still getting blue screens), the problem began to spread outside of the games and into basic applications. I tried to fix and figure out what was going on, but the time between crashes kept getting shorter and shorter. Eventually, I couldn't even get to my desktop without using debug mode. Under the assumption that my quick fixes along the way were only adding more problems, I decided to just reinstall Windows. It didn't help. I was getting anywhere from 20 minutes to two hours of activity before crashing. Since the problem was continuing I had to rule software out as the cause. Assuming it was a hardware problem, I ordered replacement RAM. After switching the RAM sticks out I had a bit more success, but still only lasted about 5 or 6 hours before crashing again. Its been some time and I can operate for longer, but still occasionally get a crash outside of a game. Then I started experiencing an issue where my programs randomly end on me. Firefox, AIM and Steam being the most noticeable and annoying of them. Painfully had to retype messages like this on tech support forums elsewhere. Most recently, my computer suddenly (usually when I have various things going on at once) locks up; the screen stays stuck on whatever was showing and no inputs can be made. All I can do is a hard shutdown. The other problem of applications closing is prevalent. I'm attaching the dumps that I've both gotten recently and salvaged from before reinstalling Windows. I'm also putting text files I saved from Windows' reports of stop errors (some from multiple instances on the same days). If anyone can contribute anything to my dilemma, please post it here.
