Hi guys, I purchased a GeForce 7600 PCIe for my system. I loaded the card in the system and everything seemed to be ok. My computer froze while on it, it froze while it was just sitting there. So I made sure I had the latest drivers and everything and the card is still doing this. What could be the issue that I am missing? The card has SLI technology, does a motherboard have to be ready for that in a video card or does it matter? Very lost with this, as the card functions fine and then it just locks. Also, I have windows Vista, and alot of people keep telling me that is the issue. But I have Windows Vista on another PC that just got a video card upgrade to PCIe and it has no problems at all. Thanks for your help.
