My mouse pointer has suddenly grown a block of fine black lines about 5/8" deep x 3/8"wide. It has also stopped working. It moves around the screen, but won't activate anything I click on. Re-seated the memory chips, zapped PRAM NVRAM & SMC, did a complete re-install after zero-ing out the hard drive. Still happens.

Do you have access to an external monitor? If you do see if the problem show up with it.
Many in this series had issues with the GPU chip. NVIDEA had a bad run of GPU's and Apple had a recall on them. But that recall has expired.
At this point I don't know if it would be worth the costs to replace either the screen or the GPU depending on what you discover plugging in an external display. Sorry ;-{
