computer boot problem

Hello, I think I have an idea of what is wrong, but I'd like to know what other people think the problem with my computer not booting is. Today my mom told me she was playing around with the wires in the back because the LAN cable was out, but it was only the cable modem restarting. Then the computer suddenly turned off. When I got home, I tried to turn it on, but the monitor wouldn't turn on (it turns on automatically along with the comp), and there would be no beeps. So, I though at first I could atleast see if there was a message telling me what was wrong. But my video card (PCI) wasn't sending any signals to the monitor to turn on. So i switched it to the integrated video port, and that worked, but then the computer screen has these green and purple lines across the screen in certain spots all the time. So suspecting the RAM chips, i took one off, then the other, then both. Again, no beeps.
So, I'm assuming the motherboard is fried, but from hearing this, is there any other opinion that anyone may have? Thanks for any suggestions!

take it you have an additional PCI graphics card as well as integrated graphic on your mother board? and that you plugged your monitor into the intergrated port - have u taken your pci graphics card out???
what makes u say your pci graphics card wasn't sending messages to your monitor other than the monitor wasn't coming on??
are u able to enter the bios?
and does the system boot up?
and have u taken out all addition pci cards and disconnected all external cables and devices?

Sounds like your video card is screwed..can you disable onboard video either in your bios or a jumper on your MoBo. Also, boot into Safe Mode and remove all graphics cards in Device Manager, reboot and reinstall your PCI card.

Lester,

Sounds like a loose connection or monitor has gone down.

Trouble Shooting steps I would take.

1. Check that all cables are connected correctly.

2. Try monitor on another System.

Others will follow with more suggestions.

Ok, i should have mentioned that I did take out the PCI card and connected the monitor to the integrated one instead. With the PCI card the monitor wouldn't even go on, and with the integrated it does turn on, but those purple and green lines show up. Im actually using my old computer right now on the same monitor, so i know it's not the monitor. Plus, I can't get to any sort of screen at all. No Bios, no Windows boot, not even the messages that count the amount of RAM i have. Nothing. Just the green and purple lines. It never beeps like it used to.
From the inside I see that the CPU fan still works and the CD player still checks to see if something is in there, and I did try to boot from the XP cd, and nothing. I hope this explains what was missing from my last post. Any suggestions now?

That's a fair test and with what I read, you have some possible motherboard/cpu failure. I'd continue removing what's not needed to get a video display. No hard disks, CDROMs and such.
