I've encountered a frustrating problem after upgrading my motherboard. Back in November, my PC shut down unexpectedly, and it turned out to be the motherboard. I replaced it with an ASUS TUF A520M, which seemed fine at first. However, now I can't restart or shut down my desktop without having to open the case, reset the CMOS battery, and force the BIOS setup. I discovered that my CPU, a Ryzen 5 1600, isn't officially supported by this motherboard, which is likely why it fails to POST. I can manually boot into BIOS and select the boot device, but it's a hassle. Interestingly, my previous Gigabyte motherboard worked well with this CPU despite the lack of official support. Is there any workaround for this issue? I can't return the motherboard since it's been over 30 days. Any advice would be greatly appreciated!

It's pretty odd that it boots but doesn't POST normally. Are you sure it’s just the CPU issue? Usually, if the CPU isn’t supported, it won’t boot at all and you'll see a mobo error message. I recommend checking out different BIOS versions. Start with the latest one, and if that doesn’t work, try some older versions.
It sounds like your motherboard doesn't support your CPU at all, which complicates things. Have you tried tweaking the boot settings? Maybe adjusting the boot priority could help. Otherwise, you might be out of luck with a fix for this issue.
This issue has come up with some budget AM4 motherboards. While AM4 CPUs were supposed to be compatible for a long time, the BIOS space can get tight and newer updates may drop support for older CPUs. Some higher-end boards come with a bigger BIOS chip that keeps compatibility. It sounds like your motherboard is one of those that just skipped older support altogether, which unfortunately means you can’t really fix it.
