Buildapc

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!
