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

Hi Robby, I suspect the Video card.

Boot off your original Install Disk while holding down the Option key at bootup to select AHT then run the extended Apple Hardware Test. Some models have a separate AHT CD.

Get Temperature Monitor - 4.51 to see if it's heat related...

And/or iStat Pro...

If you have any temps in the 70°C/160°F range, that's likely it.

Hey viad nice to know I'm not alone in this world, but I just don't see an easy fix for this. I can't imagine that its the graphics card. Screens such as the front loading screens (gray than gray with Apple and then Blue) - all seem to come up fine, as does QT Movies, so why then just the cursor?

What's Applejack and do you suggest that I get it and run it?

Thanks
