The LEDS and components all stay on. Ive had the computer for a couple weeks now and everything has been working fine no errors until now. If you have any ideas please respond to the post

Parts:
Ryzen 7 1700X
ASUS B450 F Gaming ROG STRIX
MSi RTX 2070
Corsair H75 AIO Cooler
Corsair Vengeance LED 16 GB (2x8) DDR4-3200
Corsair TX650M PSU

Not sure if its a faulty PSU or what. If the issue persists and I cannot find a fix Im going to RMA all the parts and go back to prebuilt.

Thanks for your help.
 
A quick update: I used to wire the fans surrounding the radiator to CHA 1 and CHA 2. I swapped those to cpu fan and cpu opt with very little success. Everything else is on stock settings and I never really fiddled around with bios. Temps run fine when the PC is on. The monitor loses signal and the PC stays on after roughly 30 min the last time it happened
