I have installed a Zalman VF900 heatsink/ramsinks on an evga 8800gt and the card is spitting out garbage to the monitor. I cleaned everything with 95% rubbing alcohol and a microfiber cloth, stuck on the heatsinks, applied thermal paste to the GPU, and installed the GPU cooler. The MOSFET heatsinks will have to wait, as i wasn't privy to needing them prior to be purchasing it (but will not run under load until i receive). I'm guessing i did something to damage it along those lines. Any ideas?
