Did you shut down the machine before pulling it out??I pulled the vid card out and replaced it with a known working vid card.
Well if you're OCing that much (and you're not an idiot) then you pay attention and you'll notice stuff like its not booting properly or you get artifacing... also unless you're running a BIOS hack (for which you'd know exactly what you're doing) then any OCing is post-boottime.ya lol vid cards dont usually do that unless u liek OC way way beyond there limits or something and teh mobo just cant hadle it enought, i think plz correct if wrong
