My machine has a Biostar P4M900-M4 (v 6.0) mobo and everything checked out
fine in Device Manager (drivers, etc.) and onboard sound (Realtek Hi-Def
Audio) worked fine until I installed a Gigabyte GeForce 7200 GS PCI x-16
256 NX72G series video card. Then the trouble started. I lost onboard sound
and the PCI slots were disabled, meaning the PCI LAN card and a PCI Firewire
card were no longer listed in Device Manager, and would not work. Audio
Devices are not listed anywhere. I tried downloading and installing drivers
for everything I could think of (mobo, chipset, the vid card, Realtek, etc,
but no joy. I removed the video card and *everything* went back to normal.
Running XP Pro SP2, with *all* updates. Intel P4 3.00 GH hyperthreader, 2 GB
Crucial dual channel RAM, 320 GB C Drive & 750 GB D Drive (both SATA 2) &
JustLink IDE combo drive. I hope this is enough data to help with anybody's
possible analysis. I've Googled every possible way for info with no results.
I'd really appreciate some help here from the resident experts!. TIA
Sound like your mobo don't like your new video ?
have u try update BIOS for your mobo ?
