i changed the driver on my vid card(gforce 5200) and when i restarted the comp. all i see is to begin,click user name. I think the prob. is itd to big to show me the users on the screen.Tried hitting tabthen enter but no luck.I have my driversbacked up on external and plenty of comps here but dont know what to do.I thank you for your time to read this but if you dont have much patients please go on to the next peson as i am dislexic and a bad typer,the worst possible combo for chat on comp. lol

try going into safe mode an uninstall the drive or rollback the driver in device manager .
get to safe by hitting f8 on bootup
