My husband recently upgraded to an AM4 platform.
His issue is that there is no display. The gpu fans look like they are trying to start, but cannot. Additionally, there is no POST sound and the power button, while able to turn on the pc, will not turn it off. The lights on the motherboard work, as do the cpu fans and case fans.
I told him i think its a short, but he says the case has preinstalled standoffs. My other suspicion is a bad PCI-E port. It is a used motherboard.
Specs:
Processor: Ryzen 1700
Motherboard: B350M Gaming Pro MSI
RAM: DDR4 XPG Adata
GPU: GTX 1060 6gb
Also tried: Radeon R7 250
Thanks in advanced!
Edit: Oh wow so many posts! I'll try various solutions and keep you all updated on what work.
Like the others said, double check your connections. It's easy to accidentally not plug something in all the way. Also, an extra preinstalled standoff wouldn't be out of the question and I have had that happen, would be worth checking out as well. You didn't mention what power supply you are using. New/used? Older used? Can you test the power supply on another computer to help rule that out?
