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.
When you say he upgraded to AM4, are we just talking new mobo? New CPU as well? If you have any other compatible known working hardware you can try to swap things around to narrow down where the fault lies (i.e. try swapping out just the PSU, or just the RAM, or just the GPU). In addition to what others said about the standoffs, you could test for those as an issue by removing everything from the case and doing a makeshift test bench on the mobo box if you still have it and see if it boots then. Could even just be a matter of needing to reseat some connection.
