This just Started happening recently. My game Has a Ton of broken/missing polygons. Alot of them are really stretched out across he screen. and juts recently everything had Snow and then turned into a disco type area and my Buff icons got huge and stay upfront of the screen.

My comp is -
Windows XP64
Intel I5
Gts450 vid card
4gb ram


The computer and case is icecold. so i know its not overheating
