My cursor is being followed by vertical lines

My cursor has a little box behind it (ie to the right and below) made of up 4 columns and 8 rows of tiny vertical line. These lines then migrate to the dock and the menu bar.
I Have:
repaired disk permissions
reinstalled tiger
then repaired disk permissions again

God I hope this is not a hardware problem, but something with the software or a virus.
Thanks in advance

Applejack...

After installing, Reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...

applejack AUTO

Then let it do all 5 of it's things.

The 5 things it does are...

Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.

At least if it doesn't fix it, it'll eliminate a few questions. 🙂
