X51 R3, turns on, then turns off

Hello, I am having a problem with my Alienware X51 R3. After noticing my computer wouldn't turn on I saw the power cord had come unplugged, but the computer screen stayed black instead of booting after it was reconnected. I tried first a power drain and then clearing the cmos, neither of which fixed the issue.The computer now shuts off a few seconds after starting up to a black screen. I would appreciate any help you can give.

Any flashed on the Alienware head? (Power button).

Nope, no flash on the power button, it stays solid white.

The splash screen doesn't come up, F12 doesn't seem to do anything. I also should add it's staying on longer than I realized it was, I timed it and it's a little over a minute before it shuts off again.

Can you try running pre boot diagnostics and see if any error codes show up?
