PC isn't booting, strange issue.

[Kelly Dooms]

I have an older gateway machine, and It had been sitting for a while until I got it back up and running with a new HD display. Upgraded ram etc. Ive been running it for a few days without any issues, but today was different. I had left the PC on while i was out, and came home to BSOD on the display, and rebooted the PC (not catching what the error codes were, DUH). Fans came on and there was one short beep and the fans started to slow like normal... but no display...

I shut it off and unplugged it, and held the power button for a minute, and plugged it back in. Windows started to load, but then screen went black and nothing. I tried to restart it and nothing would display on the screen. When i attempted to boot and it did it's single beep (which makes me think it posted) I wondered if windows loaded so i attempted to get sound out of the pc, with no luck. Also at these points i was able to turn the machine off by simply pressing the power switch on the case, instead of needing to hold it in. So i removed all of the ram but one stick, as well as the graphics card and it didnt seem to act a whole lot different, still shut off with one touch to the power button. Not sure what my issue is, i would hate for it to be motherboard, but i suppose it is possible. Is there any way i could tell weather it is the mother board, power supply, or graphics card? Any help would be greatly appreciated. Thanks.

Five or six years old. Graphics card is what came with it new, ati raedon 4800? (not sure on that, just a guess) and 6gb ddr3, core i7. It seems that when i have the graphics card out and i try to boot it up, it turns on, single beep, and then eventually the LED behind the power button on the case shuts off (but all of the hardware keeps running) and nothing else happens (i wish i had a VGA cable to see if the motherboard's onboard vga port had an output) And if i want to shut the hardware off i have to hold the power button in for ten seconds or so. (this button normally stays illuminated while PC is on.) And while graphics card is in the light stays on, and pc never boots up. It is shut off by just tapping the power button at that point.
