I never had USB issues when I was using her small PC before but this time it seems to have a loose connection somewhere but I don't know where. All I know is it makes the USB disconnect sound and reconnect sound and you know depending on settings how some computers will do the flash screen where the screen goes in the opposite colours (negative screen). The screen doing that bothers her so she STILL isn't using it and I can't figure out the problem. I went into Device Drivers and there was one so I disabled it buy did not fix the problem and I can't find any lose USB cord.
