MSI 870a-g54 questions

Ok, so I have the MSI 870a g54 and it ran good for sometime. Then one day I took it to a lan party hooked it up and my Monitor wouldn't recognize my gpu, on top of that the fans and the on-board CPU Led are working. Now here is something different than what I have been reading up, when I press the power button to shut it off nothing is done I have to turn off the machine by my power supplies. Help if I can fix it.

I'm running
AM3 Phenom II x2 with unlocked cores OC at 3.6ghz
corsair vengeance 1333 at 1600*OC
Galaxy 610 GT

Also I've booted the mobo from multiple Power Supplies
