I've recently had my computer give me a few strange crashes; twice while playing Champions Online but several days apart, it just froze up, gave a graphical glitch, sound stuttering and computer restarted. Then finally, I got an actual blue-screen, giving several error codes and also referencing the file atikmdag.sys. After doing some checking around, I saw a fix that involved reinstalling the drivers, going in and manually expanding atikmdag.sy_ and replacing it. Obviously by the fact that I'm here, this didn't work, and it happened outside the game while just watching a full screen video. This time on restarting I actually got a pop-up listing the codes: BCCode: 1000007e BCP1: FFFFFFFFC0000005 BCP2: FFFFF8801118BDBB BCP3: FFFFF88005BDB368 BCP4: FFFFF88005BDABC0 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 I am currently running Windows 7, 64 bit, Professional. I have also attached the .dmp file, would anyone be able to look over this and help me find something I might be missing?
