Issues with PNY 8600GT

Hi, I am having issues with my Video Cards. I am Running Dual 256MB PNY Verto GeForce 8600GT cards running in SLi. When Playing World of Warcraft, or even using my Tv Tuner Program after about 3 or 4 hours my Screen will go all rainbowish, my screen will turn red, green, blue etc. Normaly ill restart my computer, or restart the application. I have updated my Drivers, Updated directX. here are my Specs.

  1. Welcome to the forums!

    Try single graphics card mode. Benchtest each card. Find the culprit and replace the card.
    Check the card's temperatures under stress. Increase the fan speed with Rivatuner if necessary.
    Tell us about your power supply.
    Software reinstall may be in order.
  2. Oh sorry about the power supply its a 700w Rocketfish.
