My computer (not this one) won't do anything except turn on. When it turns on, nothing comes on the monitor. The keyboard won't read, but the mouse will. Again, nothing comes on the screen. Fans do turn on though. I called HP this morning, and they said "probably motherboard issue." I also called another technician, who said "Video Card." I tried to replace, but it didn't work. If I need a new motherboard -- which one should I get- mine is a Foxconn MCP73M02H1. Preferably one from Amazon.
