Longer version of problem
My system work fine but I had always gotten a ATI control panel error when I started the computer, After increasing numerous "auto detect, entering power save" monitor going blank experences, I deciided to change out my graphics card. The one I purchased was a radeon hd 2400 pro AGP. I thought that was what I had in already and asked the guy at best buy if I needed to install the cd, He said that if it was the same,"no". I shut it down, installed the cardbooted up and the new hardware wizard detected a new PCI device. After further checkingI realized that my old graphics card was a radeon HD 2600 pro card. I went to the "add/remove" and removed the ATI uninstall utility. On reboot nothing of ATI's was there. When I ran the installation cd, it showed "no driver for this device" or the other way around, but would not install. When I tried custom install, all the components were availible to install except the 2400 driver. I couldn't check or uncheck it. When I check the device manager there is a PCI device under "other devices" with a eexclaimation mark next to it When I remove it it comes back at reboot. With ATI removed a unknown VGA device is also listed in "other devices" Help
I'm running xp sp2 on a pentium 4, 3.2 Ghz with 2 gb ram
