Game Crashes while in combat?

boscoman

So ever since after yesterdays Maintence ive been Crashing every where in there while playing, first i thought it might be the servers, but now i dont know, because everytime my game crashes the patcher wants me to verify all my files. It dosnt Happen all that often sometimes its the first 30 mins or sometimes like after 3 hours. Anyone else been having this problem or is this a computer related thing?

P.S. it seems to crash when im in dungeons and PVP instances, and sometimes at the world.
