Ok. I was going to give my buddy 9300ge to play starcraft 2 with but it would not post in his system so I tested it in mine. I was able to play many games and it worked fine on my 260.99 drivers. When I went reinstall my 9800gt I could not get my system to post. I disconnected the card many times and made sure it was connected correctly. Am I wrong to think that you can just plug and play with gpus? Never had a problem before. Is there a bios setting that I must change? The 9300ge was using the gforce boost but I turned off the sli setting before I reinstalled.
