Okay, so here's the deal. A while back, (like 6 months ago), I began to get the occasional BSOD. Since my computer needed more RAM anyway, I took this as an opportunity to upgrade to 2GB of RAM. However, I kept on getting the issue. Then, I installed a fresh version of Windows, but still encountered the problem. All of my drivers are up to date. Currently, the computer is "workable" but many hardware intensive activities will cause the computer to either completely lock up, or go to a BSOD. For example, I can play TF2 for somewhere around 20 minutes before I will get a memory reference error. Other times, it will crash and yield a IRQL error on the BSOD. According to Whocrashed, these crashes have been caused by everything from Avast, to the Windows Kernel, to the video driver. To make matters even more fun, I've run memtest86 for 7 cycles on both of my RAM sticks without any problems. so i reinstalled the graphics driver and still got the error. Additionally, there is still a memory reference error. Additionally, after the BSOD occurs, the computer will reset itself. When it does so, it will usually hang on the screen for the motherboard (that is before Windows itself actually boots up) until I manually kill the power and restart the computer. For reference the memory error was: "The instruction at "0x0116e037" referenced memory at "0x000000b0". The memory could not be "read"." Any help would be much appreciated. I have attatched some of the crash dumps as well as my system specs.
