I have an old 486 system. When turning on the power nothing happens.
I don't get any beeps or nothing on the screen. I have reseated the memory and
video card. Don't quite know where else to look. After reading several books on
PC troubleshooting the only things I've come up with are (1) could be a bad power supply,
(2) memory, or (3) video card. I've ruled out the video card and replaced the memory. How
do I determine just exactly what is going on?
