Hello all.

Thus far, my computer has been dead for about 5 days, and I've narrowed down what the problem may be, and I need a bit of help on that part.

First, the background story:
My sister, one day, happened to be playing GTA:Vice City, when the computer suddenly crashed for no particular reason. I had attempted to reboot the system, but it locked at the BIOS, not long after the RAM check. I restarted it again (Forced-restart; in other words, I had to turn off the power supply, then turn it back on.) At which point, the computer refused to boot at all. The power light went on, but the monitor just went to sleep. I forced it awake by attempting to open its color configuation menu, and lo-and-behold, I received the famous RGB "No Signal" error.

My primary conclusion was that It was my Video Card (Because I had bought a new one, recently) so I swapped it with my older one, and still nothing. I tried reseting the CMOS, and that didn't work. Swapped power supplies with this computer, that didnt work. I checked to see if my CPU pins were bent, and they weren't.

Considering that this (obviously) isn't a software problem, I'll provide my specs (The nessicary ones.)

MotherBoard: MSI-6566E*
CPU: Intel Pentium 4 @ 2.0GHz (Usless info: FSB: 400MHz, 478 Socket.)
RAM: 768 MB of PC2100 DDR2. (one's 256MB, the other is 512MB)

*A note of interest on my motherboard is that it came along with this nifty D-Bracket 2 which has 2 USB 2.0 Ports on it as well as fault reporting LED's. Why this is so nifty, is that all four LED's are red. Which has led me to beleive the following two conclusions:

1. My Motherboard is dead.
2. My CPU is fried (I never overclocked it, mind you.)

Now, the reason why I posted this, If it seems as if i have it figured out, is because I want a DEFINIATE answer. Is it either the motherboard, or the CPU? Or maybe something else?

Some help would be GREATLY appreciated.

Thank you.
