Run down all the usual culprets first...

1. are ALL your drivers up to date? (i.e. video especially)

2. is it a certain scene that is doing this or anything you do now?  If it's just one scene you're trying over and over again to render, that scene could be corrupted.  If it's more than just that one, then there's a bigger issue.

3. If all your drivers are up to date (or they weren't and you correct it and yet it STILL happens)... uninstall Vue, reinstall... sometimes lil gremlins creep in... ;)

The gurus in here should have more ideas and be better able to pinpoint what's going on...

Rarer than a hairy egg and madder than a box of frogs....
