=Problem=
I've used Maya 6.0 for a few months, than suddenly i turn it on today, and my viewports are messed up.
Can't see anything in the viewports. It full of colour lines.
Perspective port works fine for some files.
Even if I start a new file, all viewports are messed up.

My system has remained the same and no changes were made.

I've done a virus scan and reinstalled Maya, but it doesn't help.



=system specs=

Pentium 4, 3GB
ATI RADEON 9600 PRO
1GB + of RAM
120 GB Hardisk space
