I have tried the all drivers that have been available since May and I have had the same problem with them all.  And yes, the 190.XX drivers are kinda glitchy with windows, but not with any games....so far.  Fallout 3, Oblivion, Spore, and Civ IV all run fine for me.

Was suggested to use this fpslimiter by someone because of my problem.

Here is a quick rundown of my computer:

Intel Core i7 920 Octo-Core Processor 2.67ghz
EVGA x58 SLI Classified Motherboard
12 Gigs DDR 3 ram
Nvidia GTX 295 GPU
1000 Watt PSU

All drivers up to date.  Games that I have on this computer that run perfect on highest settings - Oblvion, Fallout3, CivIV

Games that crash:  Spore, occasionally.  Sims 3 - CONSTANTLY crashing to a blackscreen which it recovers from sometime, error message from windows is that my video driver failed and was rebooted.

I have been working with EA tech support until they finally gave up on me and offered me a free downloadable game from their store, which I refused.

I have been through all sorts  of troubleshooting, my GPU temp never goes above 55c when playing, so I don't believe it is an overheating problem.

When I run this fix, my game freezes and stutters after playing for less than a minute.  The only way to get it to work again is to short bar and bring it back up, it will run for another 30 seconds or so then freeze again.

This is the same thing that happens to the game if I try to force VSYNC on with the Nvidia control panel for this game.  Also noted that the game runs using a SINGLE GPU, tried to force it to multiple GPU like all my other games, but that doesn't work.  Any suggestions or help would be greatly appreciated.
