I am having an issue with the screen going black for a millisecond, and an error message popping up that says "the Nvidia graphics driver became unstable but is working now", or something to that effect. It does it every 35 to 45 minutes during use; not idle. I have the latest driver, but it was one that Windows Update flashed for me not long after I installed the beta, and it did say it was a pre beta as well.
For now I am going back to the driver I am currently using on Vista to see if that corrects the issue.
Anybody else having this problem with the beta?
