Hey there, I just upgraded my motherboard cpu and ram on, my computer. Everything booted and installed fine, now though while running it seems my usb slots freeze for a second and never recover. Mouse and keyboard lights will go out, then come back on, though can not do anything with them lights cokmpletely frozen at this point. Tried waiting it out still nothing game back. I have 4 2.0 USB, 2 3.0, and then 4 on the front of my case now plugged in. These die in sets, so if the back 3.0 fails I can unplus and replug into a 2.0 and keep going, and when that dies I can use my case's usb, though once all 3 sets are freeze, whether is was an hour or a day in between, I then have to use reset because nothing else I can find will work. The computer is still running afterwards, movies still play, games are still running, even kept a conversation on ventrilo when it froze with my push to talk button active. I have done multiple reloads, tried both Vista and 7, have made sure to fully update every driver. Have already searched and asked on the net, no replies yet, so giving this one last shot before I try to send it back and hope that was the issue.
