Hello,
I recently purchased an EVGA 660 TI Superclocked 3gb from my local Microcenter. I got home uninstalled my old ATI 5850's and ran driver sweeper. Installed the 660TI and installed the 306.02 drivers. All was well for around 6 hours I tested Planet Side 2, Battlefield 3, and Guild wars 2. All were running fine. Then I tried Arma 2 OA and the game hard locked after 5 minutes. Since that the card has been freezing the entire PC at the desktop and in any game at random time intervals. Could be 5 minutes or 5 hours. I have reformatted, ran memtest for 8 hours and used my other PCIe 2.0 16x slot. It all seems well when I transfer the card of update drivers for a few hours then the Hard locks continue and the only way out is to restart my PC manually. I ended up formating my C drive and reisntalling windows and the problem continues. I even went to Microcenter and exchanged the card thinking the frist one was defective and the second card continues to crash. Oh yea and today I installed the 306.23 drivers and still my PC is hard locking. I do not know what to do I tihnk I am going to return the card again tomorrow and either get a 670 or a gigabyte 660 ti that my friend has an confirms working.. I have never had an issue like this with graphics cards before and I previosuly ran Crossfire XFX Ati 5850s. I have found people on other forums with the same issue and have heard the 660 Ti has a bad batch out there so many cards may be broken from factory. If anyone knows of a way to fix this issue please let know. Or if you are having the same/similar problem please post about it.
