Flash crashing Nvidia drivers constantly

Almost every time I have more than one instance of Flash open, like two youtube tabs, my nvidia drivers crash and reset. Even weirder is if I have one youtube tab open, and I or someone else just links a youtube URL in TeamSpeak chat my drivers will crash. I tried doing this with flash uninstalled and there was no crashing.

If I have a game running in the background and I open youtube, there's almost a 100% certainty that I'm going to crash.

My hardware:

i5 2500k @ 4.3 GHz

16GB DDR3

2x 670 GTX in SLI

Windows 8 x64 (all available windows updates downloaded and installed)

Flash 11.5.502.135

Nvidia drivers: 310.70 WHQL

I guess it's worth noting that this also happened to me in windows 7 x64.
