No, I have not made any changes to the system since the first couple of days. I just installed some apps when I first got the computer and installed the free antivirus software that came with it (Webroot).
Unfortunately I don't have a USB keyboard, but like I said the problem just happens randomly with no other indications. One second, the keyboard is working fine and then the next it stops working completely. Is there any other way besides seeing if the problem resolves when I connect a USB keyboard?
