BSOD playing Team Fortress 2/using After Effects cs5.5
I'm running Windows 7 Ultimate x64, and its a full retail version. The hardware is less than six months old, as well as the OS installation, but I just reformatted and installed again hoping it might help (alas: it didn't).
This is the first time I've encountered this issue, and I haven't recently changed/added/removed any hardware except for adding RAM a little more than a month ago. It started while I was in Team Fortress 2, and gave me the "DRIVER_IRQL_NOT_LESS_ OR_EQUAL" error on the BSOD. When restarting, I got a screen that listed a bunch of my system info and at the bottom said checksum bad error (something like that). So I tried a suggestion I saw online of changing the onboard battery as it may have gone out. That didn't seem to work either: so I reformatted.
I've attached the files to this thread. This is my most desperate hour... Help me windows seven forums, you're my only hope.
