THanks, but i've already done this. its alot easyer if you just let it overheat too- put a index card in the slot between the CPU heatsync and the fan shroud, the gpu stays extra cool, and the solder remelts on the CPU dies

But anyways you think its the ana eh? I'd say not, i ran halo3 perfect, i think it has something to do with GTA 's graphics overloading something, if i go back to the dash (in-game) let it sit 20-30 sec and go back to the game it works for another 10 minutes. Knowing this got any more ideas? Sorry about the code problem here's the link:
