Hi everyone, Recently my 8800GT died and for the moment having to use a 3450. After uninstalling the nvidia drivers then installing ATI's catalyst control centre, Windows has been telling me there was a host process error. Then the windows theme would change to windows 98 style and I'd keep getting the error. So I did a reformat because I was bored but I still keep getting the error and it says it is caused by an nvidia driver. I'm assuming it is my 780i chipset driver and when I try to uninstall it I get a message saying Error 2 - Cannot find the file specified. So I reformated again and tried a different version of the driver and still I get the host process error and when I turn on games like rise of nations the game freezes up and the computer crashes completely. I'm completely stumpted can anyone give me a hand.
