My GeForce 4 Ti 4600 (2 1/2 years old) recently started having trouble. Whenever Windows loads, some weird pixelation occurs. Once Windows loads, the screen then goes blank. Let me mention that it only happens when color is present on the screen. The black & white parts (i.e. BIOS messages) have no trouble. What I've done so far:

Cleaned GPU fan
a) Removed the GPU fan and cleaned & dusted it
b) Removed the old thermal paste/compound from the GPU core, using rubbing alcohol.
c) Reapplied thermal paste/compound & reattached the GPU heatsink/fan.
*Pixelation actually got a little worse.


Tested video card on another computer
*Same problem occured

Would getting a GPU fan help? Or, is it too late to do anything? I've looked all on the board, and none of the power cells are busted. So, what do you think?
