tried that, failed
Mmmm. That means you may need to disable the device(s) - one at a time - from the BIOS. A bit more work. Be sure to note the original settings so you can set them back after testing.
But you get the picture here, right? Some device driver may be gumming up the works and you need to go down the list and turn them off and on, or disable them, or uninstall - until you find the offending source.
That is IF it is a hardware/driver issue, which is just one of the possible causes.
