Umh.. So, I have had a lot of BSoD's on my XP SP 3, and on Win7. Atm I have XP SP3 installed, so now I will try to fix this for sure. First off, I have updated my video card driver and my audio driver from my manufactors website (XFX), and still I get this error. CPU: Intel Core2 Quad CPU @ 2,40GHZ Motherboard: XFX NFORCE 680I LT SLI INTEL SOCKET 775 DDR2 Ram: Dont remember the speed, but 4 sticks each @ 1 GB. Relative new ones (1 year). GPU: GF 8800GT 600M 512MB DDR3 DUAL DVITVPCIE PSU: Umh.. Model number: NQ-4775-700 , 700 Watt OS: Windows XP x86 DANISH SP3, dont know the build So, I do not know how to upgrade my BIOS, but I do not think it is that important. I got through some tuts and one of them told to install SpeedFan, so did I. Here I think the tempatures are really high, but I am not sure, here it goes: GPU: 55C System: 19C CPU: 47C AUX: 37C HD0: 37C Core 0: 60C Core 1: 51C Core 2: 60C Core 3: 51C At this moment I do not have any games or so running. Also it is always when I play games like The Sims 3 or Warcraaft III, that my computer gets BSoD! Do not know if that is important, but I think so. Also I have a minidump of the BSoD if nessasary, attached. Another thing, my system did not crash the first year, but in the last couple of months it happend frequently. Actually happend because of reinstalling Windows, so might be a driver problem. Please let me know.
