As for your other problem, it would help if you had specs in your sig.
What drivers are you using? Did you properly remove your previous drivers? Are you checking to see whether or not your GPU is at 100% load while gaming? Is it running at 3d clocks while gaming? Temps?
You need to give us more info so we can help you isolate the problem.
3770k stock, Maximus V Formula, 2x4GB GSkill Ripjaws 2400@1600, Sapphire 7970 stock, Intel SSD 520 240GB, Ikonik Vulcan 1000W
Clean installation, 1 day old. New drivers (12.4).
It runs 3D clocks while gaming but when the fps drop happens, the Afterburner G15 app says it is at 0% GPU load. Temps are OK, 60°C max
Hope this helps to isolate the problem
. Thanks for your help.
