hi, Well, perhaps as last resort, try the following: - if you haven't upgrade the bios of the motherboard, try to update it and see if such bios upgrade helps; - I don't know if it helps, but did you try power-cycling your modem? - Did you only use the VIA sound onboard drivers from Asrock's site, or also from VIA Technologies' official site? VIA technologies has the latest driver (Nov. 2012) for your onboard soundchip which may solve the issues for you; - try to use different PCI slots (there are 3 on your Asrock motherboard) for the PCI network add-on card. See if such switch from PCI slots helps; - Did you try clearing cmos/bios with "jumper" (by shorting the specific pins on the motherboard with a jumper) Read the instructions for this in the booklet for your motherboard. In the past clearing cmos did help me sorting out issues with my nForce 3 motherboard.
