I have a HP Pavilion ze4300 laptop. Everything was working normal and then one day I turned on the laptop and the computer keeps going straight into the system setup. Once that screen opens I can't do anything, the keyboard doesn't work. I plugged in a PS/2 keyboard and turn the computer back on, and it boots into Windows like it should. I ordered a new keyboard for the laptop and when it came in, I installed it with the same results, booting straight into system setup and keyboard not working. However, now, if I plug in an external keyboard, it only works about half the time now. Does it sound like a bad motherboard or another issue?
