Hey all,

I moved to a new pc case and my msi z87 gd65 is now giving me a hard time. on startup it is saying that some usb devices are unrecognized, and i will get error code 99 and 9c before it boots.

i think i tracked it down to a couple usb ports on the back. all devices still work fine.

other than going out and getting a new mobo, what else should i try?
