PSU or motherboard failure?

My computer powers on but nothing displays on my monitor. Only 1 fan at the top of my case powers on while the rest don't. My GPU's fans turn on but they seem a little slow.

Holding down the power button doesn't turn off my computer so I have to switch off my PSU to turn my computer off.

Before all of this, I would have random spats where my computer would just basically shut off; the tower would stay on as well as the fans and everything but my display would just go away as if I shut down my computer.

I'm thinking it's my PSU but could it be something else?

Also to note, I tried turning on my computer a few minutes ago and the one fan on top started to turn on but then stopped and then eventually started.

The TX750 is a very good unit and strong enough.
I would not suspect the psu as a problem.
Are all of the power leads securely inserted int their places?

See if you can't borrow a known good psu to test with.

At this point my suspicions would lean toward the motherboard.

Overall, yes the computer lights up. It lights up but only some fans turn on.

Perhaps it was a loose cable or something as I have resolved the issue and my computer is booting up again.
Thanks for the help! I'll hope the problem does not persist!
