Monitor stuck in standby..?

I recently found my computer monitor stuck in standby after booting up (the best case scenario after tooling around inside to fix it, the motherboard screen).

Prior my motherboard gave one long beep, and three short to let me know that the memory on my video card was bad (So the booklet said), so I replaced my Nvidia 6200 series with a NEW 8600 series.

The computer worked on it's initial boot, prompting for software for the new card, I declined since I planned to format and replace the old drivers.

Now, it seems no matter how many times I take it apart, secure, tighten, and switch around the the power cords (everything else is plugged in according to the booklet for my motherboard) the computer monitor does not advance past standby mode, even though EVERYTHING is connected and powered.

The only other information I can give is that prior the chipfan died, and I used to get a prompt to check it, skip, or go to setup. The local stores only offer a heatsink replacement (not fan), so I'm going to get by and disable the fan from the setup menu...

That is if I can ever get past standby.

1. Yes, everything is getting power. There is a delay to power down, which hints to this. When everything is not connected, I can press power and shut off within seconds.

2. Looking for another power cord.

3. Going to check another monitor tomorrow, if possible.
