so i play bf2 for about ten minutes, pwning n00bz and whatnot, and then bf2 crashes to desktop. it didnt do this before i did the watercooling, and i just erased my voltmod, so wtf. this has happened every time. i cant pwn noobs for only 10 minutes at a time. the temp for the 7900gt after playing was 39c, so heat isnt a problem, i think. any help?
