I'm getting the kernelbase.dll appcrash error when I start up dirt 2 and F1 2010... Same thing with Fallout 3 too, means it could be GFWL, but reinstalled GWFL so many times and restarted, cant count how many times... Done sfc /scannow in cmd, restarted. Installed all the stuff in the redist folder of my game disks. Still the same. Is there anything else I can try? Running windows 7 64 bit, I7 920, 4GB corsair ram, 2x GTX 460 768mb's. Disabled SLI too... I used to be able to play both these games, don't know why but I cant play them all of a sudden, been going on for the past few months.
