Help I upgraded my video driver and now get out of range

[iocane]

Ok I just put a fresh Ubuntu only install on a new desktop I built and when I went through my updates it updated my onboard video card and now I get out of range on my monitor after the Ubuntu splash screen. I'm kind of a noob when it comes to linux and I didn't create recovery disks yet. Do I have to reinstall?

Tell us first more about your system: what kind of videocard you have installed and such. Also a good word of advise the next time when you post here, always add as much as possible info about your system/problem/error/etc.

my motherboard is a gigabyte a55m-ds2 and my processor is a amd a4-3300. The video card is inside the processor and is an ati radeon hd 6410d my screen is completely blank after the out of range error on the screen. Also I am still running natty narwhal I didn't get a chance to update to the most current version
