I have an A7M266 Mobo and I am having video lockups when I am gaming, on the board I have a GF4 ti4600 video card. Today I stuck in a GF2 MX PCI video card and had no lockups, also I know the GF4 card is good because I stuck it in another machine and had no problems. Are there any known issues with the A7M266 mobo's and the AGP slot on it?

If you are using the stock bios you need to upgrade it to the newest version. Support for the geforce 4 was added in that version. Flash and you should be fine. Good luck.
