Just installed a USB hub on my computer running windows xp sp3. The next time I powered on the computer, it just banged before even the motherboard logo appeared or my USB keyboard and mouse got power.
it seems to me like its trying to boot from the USB hub. Naturally I would change this in the bios, but I can't even get to them. It does the same thing whether the hub is plugged in or not.
When you say "banged" do you mean an audible bang?
