My pc shuts down after a few seconds and monitor says no signal?

Question

i just installed a new Dial up modem onto my computer, it didn't fit well so i rearranged some of my sound cards and other cards...etc. when i plug it back in and turn on the computer, the monitor does not receive a signal, and then the computer shuts off after a few seconds.

Answer 1

Probably a problem with PCI interupts (IRQ).  You are going to have to move things around and figure this out via a process of elimination... or take it to a shop... or upgrade to DSL (which may be cheaper than paying a shop to fix this issue).

Start the process of elimination by starting out with just the basic cards you need (the video) and add from there.

Answer 2

make sure all the cords are plugged int the tower and screen
