Hi, my nvidia driver keep crash while im not playing bf3. What i meant here, i play bf3 without a problem crash or freeze or whatsoever but once i go to windows and try play some mp4 or wmv movies the driver will crash and make my pc rebooting but not with mkv or avi. I did the clean install where i use driver sweeper from 280.xx to 285.xx (latest drive now).
My GCU 560TI Hawk, playing on 1920x1080 with auto settings.
Should i try reinstall the driver?

try uninstall and reinstall back..

I always get the entering power save mode, and its rebooting my system. My.monitor is dell u2312hm. How do I disable them?
