Well, that was short lived. I just turned on my computer after getting home from work and the video went all psycho again. This time though I could actually read the message on the screen and I got a Windows 8 message that said the nvlddmkm.sys caused a problem and it did a memory dump.
I guess the card is kaput, gonna send it off I guess, unless anyone else disagrees.
Before sending back card, I suggest send your memory dump to ManuelG guy at nvidia forum or mail it describing your issue, linking this thread link at following email address:
You are not the only one facing this issue.
Only two things worked for me:
1) Using Windows 7 64-bit stick with 314.22 WHQL driver
2) Using Windows 8.1 Pro 64-bit stick with latest WHQL. It does happen on Windows 8.1 as well but Microsoft has remarkably improved timeout device recovery functionality, I just get single white flash and then all OK and tooltip show that driver got error while sometime my mouse start lagging but I get enough time to restart and it all works.
All who thinks that it is specific to you, I have to say sorry you are not alone in this boat:
Figure out yourself:
Nvidia also provided test driver for people facing this issue yesterday:
You can test them as other one reply comes from nvidia forum, they say with new WHQL driver 330.5 situation is not that much bad (at least for OS with better Timeout device recovery functionality). As I mentioned in point 2 I made with Windows 8.1 scenario.
