What else is connected to the other usb ports? Your phone (charging the battery) or a camera or ipod. Remove non-essentials from the usb ports while you use the HDPVR, also, you have to use the same usb port every time you use it.

The vieo card requires 650 watt PSU so the 750 watt PSU might not be having enough surplus power for the rest of the componnts, I'd suggest about 900 watts PSU for this rig.

The total input of all the hardware should equate to 80% of the total output of the PSU to allow for power surges and extra power should it be required by the system.
