I was recently trying to overclock my computer when I realised that I couldn't use my SATA ports 1 and 2 on my MSI Nforce3 motherboard because the frequency isn't locked on those 2. I then switched my HDD's to SATA ports 3 and 4 and my PCI lock to 67 and now my Audigy2 sound card quit working. I tried switching PCI slots, switching the sound card, switched my SATA back to normal and reset BIOS, changed PCI lock between 66 and 67 and I have had no luck. The card also will not show up in my Windows Device Manager. I am really frustrated and hope someone can help so I don't have to go out and buy a new motherboard. Thank you.
