As I try to boot the computer, it plays the boot-up sound for a literal second then immediately shuts down.
I got the machine like this.
Edit: some changes

Sadly, this sounds .like the GPU board has failed iMac Intel 27" (Late 2009 or Mid 2010) Graphics Card Replacement

Take the cable (AC) out of the unit and depress the power button for 10 seconds. Plug the AC back in an try to reboot. If it exhibits the same no boot or works for a short time, then shuts off, probably is the power supply board. Just guessing :)

So you see any image at all?
Do you see the Apple Logo and then the progress bar about how long is the bar (mm)
If you don't see any image let the system sit for a good five minutes. Then take a flashlight placed on the screen at a sharp angle do you see a faint image of your desktop and its icons?

No logo just flashes a white screen and stops the boot-up
