“Out Of Range” graphic error in Ubuntu

I loved Ubuntu until i got this problem
every time i try to boot Ubuntu. i get an "Out Of Range" error. Meaning that it has something to do with my graphics capabilities, but my graphics card is fairly new, and i installed the drivers through the Ubuntu menu.
My Graphics card is ATI: Radeon HD 4350. and help will be awesome, because i really don't want to uninstall Ubuntu and reinstall it.
It takes about 4-5 hours just to download the updates.
Please help
