Usb ports are intermittent

just built my new PC everything worked great for the first week or so now all of a sudden my mouse and keyboard will randomly quit working, after 10 seconds or so they start working again it usually happens in game all though it does happen other times just not as often, as im making this post it is actually happening more frequently 3 times in last 10 min.

The build
ASRock Z77 Extreme6/TB4
Intel Core i5-3570K Ivy Bridge 3.4GHz
EVGA GeForce GTX 560 Ti FPB x2 one is 6 months old
Antec High Current Pro 750
G.SKILL Ares Series 32GB (4 x 8GB) pc3 14900

cooling is not a problem in a nice antec case lots of fans cpu is using aftermarket heatsync temps from 14c to 28c

I have updated bios as well as asrock fast usb utility, in device manager have also set all usb hubs to never turn off

bad memory? bad mobo?

sorry not sure if i posted this in the right place just looking for help
