Hey guys. I got a GeForce GTS 250 Series graphics card a few months ago. I was able to play my games, like Oblivion GOTY, on ultra high graphics just fine. Then I bought a new case for my computer, switched everything over, and now I can only play on low to very low graphics. I thought it might be a bug on my PC so I reinstalled Windows XP, wiping everything. This didn't fix the problem at all. Does anyone know what might be going on?
