I have an Asus P5K-E Mother Board. My case has an Antec 500 Watts Earthwatts Power Supply which is less than 6 months old. Your right about it only happening after a file transfer. This problem might be the OS not fully compatible with my hardware. I have the 64bit windows 7 Ultimate. Maybe fixes are on the way as we report problems or concerns on forums like this. I hope Microsoft reads some of the many posts on this forum.
Just for testing remove all other USB devices and do a file transfer.
See what happens.
If the problem doesn't occur, it might be a power issue.
(too many USB devices draining power from the same internal USB host controller)
If that's the case, try switching some of the devices to other ports (other internal USB host controller)
You can see the power consumption on a host controller in device management.
