Comment 326 for bug 204996

Sometimes my desktop just freezes. and there are some vertical blue dotted streaks across the screen. The mouse works but nothing on the desktop can be clicked.

Assuming some compatibility error due to any recently installed software, I did a clean install of the OS. But the proble still persists.

Though it occurs randomly, it usually occurs while I am using firefox browser 3.0.3.

This is the first time since I am using ubuntu (since version 6.06) that I am encountering an issue like this.

I am unable to give a screenshot becoz even the print scrren functionality doesnot work during the freeze.

Can anybody suggest a solution?
