Here's what I have. First, the monitor shuts off, or appears to. I check connections, jiggle wires etc., then the computer reboots. Another time monitor freezes, lines across the screen vertically, then the computer reboots. Many things run through my mind, monitor problem, but I switched monitors and that's not it. The case connections are good; I've undone and re-done; everythings secure. It's an ASUS MB with a built-in video and audio system. I've considered the RAM, but I don't get a hint of that actually being the problem.
I'm up for any suggestions. How can I best trouble shoot to home in on the problem? Any help appreciated.
