I just recieved my newest graphics card in the mail today its the Gigabyte Geforce GTX 670 Windforce 2 GB graphics card. I removed my old card and uninstalled all of its related drivers (it was an AMD 6870) and then proceeded to the nvidia website to install all of the newest drivers for my card. installation went smoothly and I immediately jumped into far cry 3 after all of my updating and restarting and such was complete. I found that I could only play for 5 minutes or less when it would freeze, sound picture and everything so I would have to do a forced shutdown my holding down my power button. I thought it was a freak incident then found it to continue happening. I went from running it on 1080p ultra dx11 to 720p low dx9 and the same duration would happen no matter how i edited the settings. I then went to borderlands 2 and planetside 2 and found the same issue happening there only i would be able to play for 20 minutes or so before the freezin and restarting. I then went in and removed all the driver information and installed older versions of the drivers and found the same issue was at hand. so i played around with installing different versions and always made sure they were clean installs. I am now again running the latest version and dont know what to do. I went through and it looks like all of my components are up to date, so whats up? Also, I made sure i had the latest version of direct x 11 My specs: Windows 8 64 Bit 10GB Ripjaws Ram Gigabyte GTX 670 Sandy Bridge Intel core i3-2105 ASUS P8H61-M motherboard 850W PSU Please help!
