Stormrage: IRQL not LESS or EQUAL usually meant for me that my graphics card's temp reached more than 125 C and forced the BSOD, back in my Nvidia days. Artifacts showed up after 90 C so all symptoms point at that.

If you have an ATi card and that happened, well, your video card is probably faulty.

B3RTLE: WTF just happened? ...game was running perfect .... then the graphics starting looking like shit..last night ...then today I get ... this disk not in drive error ....then the computer crashed with a blue screen saying something about IRQ NOT LESS or EQUAL ..
