I have an MSI Geforce 4 MX4000 128 MB. We have worked through everything to figure out that something isnt right for the card with the motherboard or in the system bios. Does anyone know anything I should try to stop it freezing, especially including disabling things in BIOS to see if it works. I have a pentium 4, a P4 SGX MX motherboard, and 512 MB of PC3200 RAM. I also think that my problem might be related to the integrated SIS 650 video card in the motherboard. I have disabled the onboard video in the BIOS as well.
