I have sent an email to nvidia about this, but I figured someone here might know, too. I recently (about 3 weeks ago) got a geforce 240 gt DDR3 video card. The first driver I installed (the recommended one at the time from the nvidia website) was fine, but it would crash quite a bit. They released a new one a few days ago and this caused everything that moved (even on webpages) to flicker horribly. I went back to an older driver dated from Sept. of last year, and it, too, flickers (although not in SC2). I'm using it still because it lets me play SC2, but it's very annoying to see the screen flicker all over webpages.

Hello Volatilejohn

If the issues still occur after you apply the new drivers can you also post some information about your computer? You can find this information in the Direct X Diagnostic Tool:

Press the Windows Key and R
Type in: dxdiag
Hit Enter or OK

Click on the Save All Information button at the bottom, and create a dxdiag text file, and copy and paste the data from the dxdiag file into your reply.
