my keyboard and mouse keep freezing every so often. I ran memtest86 with no errors, checked my 3 hdd's for errors, and no errors. I have done everything that gigabyte support said to do, with no solution.I have a Gigabyte GA-990fxa-ud3 main board with a FX 8120, 16 gigs corsair ram, 3 hdd's, radeon hd 7770 video card. how can I fix this? I am at my wits end. any input would be appreciated.
