I need some help with my strange behavior of my new PC. My setup is AMD Ryzen 5 3500X MSI B450-A Pro MAX Colorful igame gtx 1660 super Klevv bolt-X 2x8 GB PSU be quiet system power 9 500W
The problem is, when first connected to power. My PC will always turn on by itself without pressing the button. But if I not disconnect the power source / turn off the PSU (normal shutdown only), next time I can turn on my PC normal with pressing the power.
And "Even If" I disconnect the power source / turn off the PSU "Not more than 5-10 minute". When I connect the power source / turn on PSU, It won't turn on automatically.
But If I disconnect the power source / turn off the PSU "More than 10 minute". When I connect the power source / turn on PSU, It will always turn on automatically.
After so many test try using other PSU / RAM / Processor / Motherboard. I find when I change the Motherboard, this problem is not happen.
But when I bring this to official MSI support center in my city. They say nothing wrong with their Motherboard and don't find any faulty there. Can you guys help me what should I do? Or maybe something that i need to do to check my motherboard. Because I'm not an electrician expert, i can't check the mobo myself. Just trial and error.
And lastly even if my motherboard is okay, is this kind of problem gonna hurt my entire setup? Or is it just some small error that can be ignored. Thx before
Update
After I talk to the MSI support center again, they show me that when they testing with their processor. The motherboard is okay and not faulty. They said that the faulty one maybe the processor.
And I goes to AMD, and they test it with their motherboard. And the result is their processor is okay. But when they test it with my motherboard and my processor. The auto on is happen again. So AMD says maybe BIOS problem.
And so i decide to don't care the problem. But just curiosity, does there ever incompatible motherboard/processor even the socket is okay?
And is there someone have same problem with me using MSI-A PRO MAX / Ryzen 5 3500X
