Solved: Display messed up after Disc Cleanup

Got a computer alert message last night that I was running out of hard disc space. So I ran the Windows Utility program. This morning, when I turned on the computer, it loaded up normaly except the display is messed up with large icons (and a message that the display resolution was set to low.) Not sure, but I must have defaulted to some basic display settings or drivers? I went into the computer control - display panel and attempted to adjust resolution, but I couldn't slide the adjustment. I searched for the display drivers, but not sure what to? My display is a Realsync model L19HMN (dvi) (my wife thinks I'm an idiot.... need your help!) thanks
