Hi, I've been lurking around Tom's Hardware for a long time, and until now, I could find answers without posting them. Yet, I bumped into a problem today that I couldn't solve with the help of the handy dandy internet forums. Anyways, today I got a GeForce GT 220 (EVGA) and I easily put it into the PCI-E slot. Thinking I was done, I turned it on and put the cd in for the installation. After using the cd to download the driver, I looked at my system settings and saw that it was still my old default video card GeForce 7100 in it. When I tried to reinstall the driver as one topic told me so, the nvidia site told me that my computer needed a 7100 driver instead of the GT driver. Why does the GT video card not pop out? I have tried using BIOS to have the main slot at PCI-E, but it still doesn't work. I also have the VGA cord in the video card, but it still did not help. I don't know how to switch the 7100 to use the 220. Help! (If I use CPUID to see the video cards it only shows the 7100) Thanks!
try to disable 7100 if it is on board graphic card.
Make sure you did plug power cable into your graphic card if it is exist, otherwise computer will use on board.
Make sure you plug VGA or DVI cable into right card.
