my wife's (i bilt) GA-EP45-UD3L motherboard recently fried (or otherwise made inoperable) a Soundblaster X-Fi Extreme Audio card. the card was some years old, so i passed it off as age. replaced temporarily with an ASUS vostro(?) to get by. two weeks later, IT ceased to function. mobo going away? i ask because my mobo (same model) now seems to have intermittent usb port problems. both are 1 1/2 yrs old. Help?
