computer locks up top half of screen lines and bottom half black

Asked by Erik Gamerl

I installed Ubuntu 10.4 on a Gateway desktop, 2.6 GHz, 512 MB RAM. The computer starts up fine. After working with any applications for awhile, the computer freezes up and on the screen the top half has lines and the bottom half is black. Any help would be greatly appreciated.

To follow-up my earlier question. The freeze seems to occur when using Mozilla Firefox, not while using other applications.
