This happens on the front and back usb ports so i doubt it could be a loose connection as the back usb ports are soldered on to the board.

maybe the usb controler is fried?

im gona get a usb pci card tomoro to test in the mean time any idears are welcome.

its not the psu or ram as iv swaped the psu with a diffrent one and iv tested the ram.

the 70+ other workstations of the same spec work fine so its not the crap hardware apart from maybe the mobo or cpu. i get cpuz info tomoro.
