When I turn on my computer, it doesn't boot up and show a message on the monitor that says "Check PC and signal cable" or something like that. I have jiggled and unplugged all of the cables to try to fix the problem but it doesn't help.
This has happened twice before and the propblem usually corrects itself if I leave the computer alone for a few weeks but I always fear that the next time it won't help. I want to know if there is anything I can do to keep it from happening.
The computer is an E-Machines that I got in 2006 but it is in fairly good condition, and has Windows XP as it's operating system.
