Recently bought a new computer. Its a gateway, AMD Athlon 4600 Duo, 2 gigs of ram, 300 watt power supply, running with windows vista premium. It had a geforce 6150 integrated video card. I replaced it with the card in the title. Now any kind of application that requires video memory simply doesnt work. Even the chess game that comes with the computer, ill make a move, then it locks up, screen goes black, then it unfreezes, and i get an error message saying Display driver (forget what it says here) stopped responding and has successfully recovered. I have the newest drivers that a BFG tech support told me to get, I removed the integrated card in the device manager. Cant seem to fix this issue, starting to think the video card might just be defective. Anyone have a clue what I can try next?
