A friend of mine is having a computer problem with a relatively new computer. He had it at college with him and it was working fine, but then he took it home and plugged it in, and when he turns it on the monitor says no signal from PC. He's tried multiple monitors on it only to get the same result, and he says when he turns it on it doesn't beep. Correct me if I'm wrong but don't all BIOS beep once on startup, and if there if something f'd up in the PC they beep twice or something like that? He's listened to it close and says he can hear the CD drive boot and the hard drive sounds like it's going fine as well. So what could be the problem here? He's checked the port in the back of his PC and nothing seems to be wrong there. I'm going to go over there tomorrow to try to troubleshoot his problem, any suggestions on what I can check for, what I could do, or what might be wrong? Thanks a bunch.
