Due to the file name i would guess its to do with the graphics card, either driver or hardware..... if you boot into safe mode (keep pressing F8 when turning on and it will bring up an advanced boot menu) just leave it running in there, if it works fine use the safe mode with networking to download the latest driver for the graphics card.... If it still does it it soundsl ike a hardware fault in which case another grpaihcs card is needed....
