Usb devices causing BSODS?

[danoliver1]

My computer has all of a sudden started BSODing when ever i connect 3 usb devices to it.
So far i have restored windows to a time a did work, Ive reinstalled mboards usb etc drivers and also uninstalled the usb portion of the system, so the comp redetects all devices from scratch, but the problem persists.
Anyone have any ideas as to what i can do next? cheers in advance.

Devices are mouse, keyboard and usb wifi dongle so powered by the pc, it was crashing with the dongle attatch, didnt crash when removed. i reinstalled the dongle drivers but its still unstable.
Pc has been fine for ages no problems the last night got this problem out of the blue. Dont think its a power issue, my psu is overpowered for the rig iam running.
