Does the problem still reproduce with the latest version of the Content Projector?
Also, i'd start by rebooting for the GPU driver installation issue.
If that doesn't help, doing a sanity check on the filesystem isn't a bad next step. If your hard disk is on the way out, corrupted files and things are often an early symptom. You may also want to consider backing up anything important first, just to protect against the possibility that putting the drive through it's paces is enough to kill it.
Check your hard disk for errors - Windows 7:

If you find and repair problems with the filesystem, then you might give the driver update utility another shot. If it doesn't help, you might check out nVidia's support to see if they can help you troubleshoot the installation failure there.
I still have the problem, yeah.
I managed to do the GPU Driver update after doing some windows updates (some of the "optional" updates, not major ones.)
I can't see how it's a issue with my hard drives. I'm now convinced it's a driver issue but where the fault lies it the mystery.
Even after getting everything updated, it's still there.
But it ONLY happens when I open a .SWF file in Flash player directly.
Opening a SWF Application program has no problem either.
EDIT:
Ok. Found the issue. Not sure why it did this but the problem was actually in one of my SWF Application programs.
It was one that has a programming Gliche it that's stopping it from running in windows and, in my efforts to fix it,
caused Flash do something funky with all my stand-alone SWFs.
No clue why it would of spread across all my SWF files like that though. It should of only affected that one program.
Sorry for blaming the program for my mistake.
