No Post After Installing in Case

[Waldo808]

1. System configuration
   • MOBO: asrock AB350 PRO4
   • CPU: Ryzen 3 1200
   • Memory: T-Force DDR4-3200
   • GPU: Geoforce 9800 GT
   • PSU: 750W
   • Storage: WD 1 TB, 2x WD 500GB
2. Troubleshooting steps you already did
   • Unplugged all connections and reconnected
   • Unplugged everything but the memory, cpu, and gpu
   • Unseated and reseated ram
   • Removed second stick of ram
   • Switched an tried other stick alone
   • Checked monitor and display cable
   • Connected speaker to listen for beeps (It didn't beep at all)
3. Any additional information that may be relevant.
   • I tested the system before installing it in the case and it posted and everything was visible in the BIOS. But after installing it and turning it on the fans spin up but nothing happens. I am very new to working on computers and this is my first build so I don't know what else to try. I plugged a speaker in but it does it does not beep at all when I power it on. When it posted before the fans came on full power and then slowed down before it posted but that is not happening now, the fans just run at full speed. The other weird thing is that it powers on as soon as I plug it in, I don't press the power button at all. Thank you for your help!

Motherboard standoffs properly installed?

 

Faulty power switch on the case? Which case is it?

I'm not connected to the power switch on the case, and I can try removing the board from the stand offs and see what happens.

I took it out of the case and hooked everything back up and now it isn't posting outside the case either. The fans are still spinning up but nothing else.
