|Asrock K7NF2 Raid mobo,Athlon XP-M 2600 processor.|
Last week pc would not boot, no beep codes could not get into bios. After much trying managed to access bios, checked and saved settings, after that pc booted Ok and all seemed well except no USB devices visible. Device manager says USB ports are there and working OK but nothing plugged into them is visible in Windows Explorer. Had a PCI USB card so fitted that and it installed OK, all USB ports on the card work fine but mobo ports still not working. Any suggestions, tried the bios battery that still gives 3v OK.
