In the last week or so,i have encountered a problem with graphics drivers failing all the time. For example, I play a game, or watch a movie or whatever, and suddenly the video starts freezing for a couple of seconds and then in quickly speeds up,sometimes i get a black screen but not always and a warning that graphics driver has stopped responding but has recovered. My graphics card is an nvidia gtx 750 ti 2gb. I have tried updated and re-rolling the drivers with clean installs(tried the newest drivers and now im using 362.0) but it hasn't worked. I checked my GPU temp using GPU-Z and its not overheating, its around 30-35 degrees when watching movies. I found a "fix" by doing something in the regedit(setting something to 8) but i don't really know to explain it as i was just following a guide on Microsoft support,but nothing worked. What the heck is wrong and what can i do to fix it?Also,i'm using windows 8.1; I have been using it for a few months,maybe even a year and no problems like this so far. Thanks in advance for all the help.
