Hello guys, i hope all of you will understand my english. I am Russian. I have my gtx 260 for about 2 months, and 3 days ago it started artifacting after playing codmw2 for about 1 hour on 60% fan speed. My temps on idle are 49-50, under load it doesent go more than 67, idle temps are high because of the 3d clock mode running allways, otherwise after switching from 2d to 3d mode the game will crash ( just codmw2). My drivers are 196.34, and i have done all the boot safe mod and driver sweeper before installing these ones. Also if these helps, sometimes i open my window to give my pc some really cold air, here outside is -30 degrees, and i am wondering if it could be because of the temperature change somehow. What else i can say... My pc is fully air cooled, i have two fans on the front( 120 and 140 mm ), one on the left side of the case ( 250 mm ), one on the top( 140 mm ), and one at the back( 120 mm ). Also my proccessor is clocked at 3.33 ghz is an E4500 and the voltage is 1.68 (is it too high?), the mobo is an p43 from gigabyte (specs) For other specs look my profile. Any help would be appreciated. Thanx for the attention.
