I have an AGP slot and PCI. No PCI-E. The card is a PCI and it fits. I had the card in the computer, and when I boot it up, it did show the stats. of the card on the screen. When I went to install a driver for it, it didn't work. I can't find the correct driver. Plus, the fan on the card had seized up. I did replace the fan. but am afraid that I can harm my computer with this card. If there is anything anybody can enlighten me to, concerning the driver, I would greatly appreciate it. Thanks.
