As some might recall, I've had issues with getting the latest drivers from Nvidia for my video card because it always crashed when I tried to use any driver newer than the 314.07.
Well the other day I updated my windows and added this fix too.
Graphics software or applications crash when they use WARP for software rendering in Windows
I then found that my audio was acting up, just in the middle of watching a flick the audio would stop. so I uninstalled all audio, video and hauppauge drivers and reinstalled, except this time I installed the latest video driver (344.75) and I haven't had any video crashes in the last two days. So...I think they got the video debacle finally fixed!
