Hi, I recently formatted my laptop (a Fujitsu-Siemens A1667G), and after trying to play some games on it (Baldur's Gate 2, for instance), give or take 5 minutes into the game, it generates a BSOD ("A thread tried to release information it did not own.") The PC used to do this as well, but the problem stopped for some reason after a while. Is there any particular reason it might be causing this? Even after I had new RAM installed, it did not generate any problems, and it is odd that the problem should recur after a format, when in the past it did not do so. It's been suggested to me to use the UBCD diagnostic tool, but I haven't the faintest idea how to use it. I don't want to take my laptop in for repair unless it's really necessary, and I doubt this is being caused by a hardware problem, as before the format it was working fine. I've attached the Dxdiag file and a zip with the minidumps. I'll be running MemTest later to see if I can rule out the memory as the cause of the problem. Please help.
