Big bad problem in vista! :(

Hello guys.. I have problem when i star gaming in vista... The problem is that when i start playing i play ~30 ~40 minutes and then game froze and show's me a message in the screen "Display Driver Stopped Responding and Has Recovered" .. I try tryed reinstall drivers .. but nothing.. I saw too much people in google with the same problem .. Can be fixed somehow ? I realy like'd Vista .. or i must go back to the Xp? Tnx you

BTW.. if is needed .. VGA: 9800GX2 CPU: Q9450 RAM: 4GB

Thanks.. and sorry for bad english

I tryed 2 games .. Crysis and Assassin's Creed .. And i didn't search for patche's becouse i saw other people with other played games that have the same problem :{

overheating???

The 9800 GX2 is quite new, and it's running SLI out of one slot it's bound to have some problems, also is your motherboard SLI certified, if it isn't then that's your problem. Even though the GX2 is a single card it uses SLI to run both cards at the same time.

My old card was x1300 radeon .. i changed all my old pc and buied new components .. and didn't use vista before i buy them

When you installed vista did it show up as supported in the approved hardware list? Sometimes Nvidia is slow coming out with decent drivers, especially where vista in concerned. I bought my gts about a month after it came out, and vista didnt recognize the card for about a month and a half later. But i would still check the ram, just to make sure that isnt the cause. After rereading your original post of the problem, it still sounds eerily familiar to what i was experiencing, and anything is worth a shot.
