I’ve got a Dell Dimension 9100 which has 7 USB slots, 5 on the back & 2 on the front. All 5 on the back work fine. 2 on the front have never worked, however a little while ago one on the front used to come out with an error message of ‘Device has malfunctioned……’ if a USB device was plugged into it, the other one on the front did not respond at all if something was plugged into it.

Now the one that used to come up with an error message has become like the other one, no response irrespective if something is plugged in or not.

All 5 USB ports on the back are in use, so not sure if that may be playing a part in there being not enough power?? for the front ports!

How do I go about getting the front USB ports both active again? As it would be handy to have for plugging a USB pen drive into, as opposed to having to remove another USB device at the back of the PC & try and plug it into there.
