I just changed my hard drive, stuck in a windows 7 cd, installed it successfully. Installed chrome, dropbox and system update. Ran Lenovo system update, and at some point the computer restarted itself, made three loud beeps (long followed by two short) and thats it.
The bluetooth light is on, as is the power on, battery, and charger lights. Screen is dead.
What happened? What are those three beeps? What do i do?
