USB hub port power surge.

Well I just got a brand new medion computer (4GB ram, 1GB nvidia graphics card, dual core i5 3.0Ghz processor, etc) about 3-4 weeks ago and have had no problems till now. The problem is when i bought the computer i got a mouse and keyboard which worked with it till about 2 days ago. I have 3 USB 2.0 and 3 USB 3.0 slots and. 2 of each type are on the back and the remaining 1 of each are on the front. Now, anytime i plug both the mouse and the keyboard into the back i get a warning message at the bottom right saying "USB hub port power surge" or something along those lines and neither device works. But if i un-plug them both and plug back in the keyboard, the keyboard works. I have tried restarting my computer. I have even tried turning the computer off, un-plugging it from the wall. Than holding the power button so it quickly flashes on and than off again (I hear this resets usb ports Link: Reset of USB port after probable power surge ) I than plug the computer back in and start it up but still neither devices work unless i unplug the mouse. I have also tried plugging in memory sticks and other devices and they work until i plug the mouse in beside them. Every now and than they un-expectedly decide to work together and than stop as randomly as it began. Any help or advice would greatly be appreciated
