I am having a strange problem with USB. A friend called and said her computer ( Compaq desktop) had made a popping sound 3 times then went off. I replaced the PSU and every thing seems to work but 2 of 4 USB ports in the back and 1 of 2 in the front. All the none working port have power because I plugged in a USB Hub with an indicator light I then get a warning of USB device unrecognized. Any Ideas for a solution?
