Viewing Flash at Max and problems with HD 5850

[fastx21]

System:
Amd Phenom II x4 955
Gigabyte GA-790XTA-UD4
4 gb of G.Skill DDR3 1600
HD, dvd drive,
XFX HD 5850 Black Edition

The problem is anything I watch a flash video (Vimeo, youtube) on max my computer will either freeze or bluescreen. So far I have only been able to replicate this problem with watching flash on fullscreen. They seem to work just fine when not maxed out.
I have updated the card drivers with the latest from the XFX site (ver: 8.702.0.0 2/02/2010).

I would just like to make sure it is a driver fault and not the card itself. Certainly it could be another part in my system but I'm fairly certain it's the card's driver at fault. Gaming wise the card runs just fine. Ofcourse I have emailed the manufacturer to see what they say.

I took a shot of the bluescreen below.

STOP 0x0000003D errors are likely caused by hardware or device driver issues.The STOP 0x0000003D STOP code is rare so there's little troubleshooting information available that's specific to the error.

However, since most STOP errors have similar causes, there are some basic troubleshooting steps to help fix STOP 0x0000003D issues:http://pcsupport.about.com/od/fixtheproblem/ht/stoperrors.htm

OK I tried to emulate the problem on a new windows 7 install and now it only happens wiht vimeo on full screen. Youtube will play fine in fullscreen (for now).

I'll try out an older video card that I have to see if it really is a video problem.
