Hi, I have had this computer for quite some time, probably a year and a half to two. I started having BSOD after several months, but it was rather rare. I noticed it happened a little more frequent about half a year ago, where I played more flash games on facebook. My computer randomly reboots more frequently than BSOD then. Eventually I have a defective hard disk, and I replaced it; I was guessing it took too much of this random reboot thing. Thereafter, the problem still persisted, but it didn't irritate me enough to want to spend maybe half a day rectifying it. However, I started playing games on my computer (not flash games, but those full screen MMRPG), and it started to happen more frequently. This time it irritated me enough when it sometimes rebooted/BSODed every hour. Having said that, sometimes I could play the whole day (like 16 hour) without rebooting/BSODing even once. After that I tried changing PSU, and also updated display driver. Not sure if I'm having illusions, but I think it became worse after updating display driver. These are the minidumps, hopefully someone can save my computer. Thanks.
