Besides the Blue Tooth problem you saw before do you have anything else plugged in or forgot to install drivers
for addon tuner card or something like that. That could also be for the keyboard and/or mouse if that's a programmable usb model as well as the lcd you have there.
Generally I see that most often with the tv tuner card in use here when still not having that taken care when the fresh installations were on but put that aside until last. One fast way however is to go into the Control Panel>Windows Updates and allow that to check for any optional hardware updates there.
