Had experience last week of this nasty bit of malware. Graphics driver kept crashing and was almost at the stage of pulling the card and starting an RMA. I thought it was TDR issues (Timeout Detection & Recovery problem) which I had read about Found out that it was actually malware that had been installed on my system after I had noticed iehighutil.exe running in task manager and then started Googling for info. Seemingly it sets itself up and uses the installed graphics card to mine Bitcoins and crashes the graphics driver while doing so. The AV I use never picked it up (MSE) and Malwarebytes also never picked it up on a scan. So just a heads up for anyone having graphics driver crash issues at this time that this might be worth a look.
