Greeting evryone!

I've always been passionate about electronics, only now I have had the possibility to explore it.

My first computer was a ZX Spectrum 48K, some keys stopped working, nothing I could do, that was frustrating. As life went on I had many device that I want to understand buit had no tools or anyone to teach me. Curiosity stayed alive. I've aquired basic tools for repairing and building, so far I've had some fun with them and I feel that the ability to make small repairs is closer. Diagonsing the problems seem like the greatest challenge now. Looking forward...

I have Asus Z170 Pro Gaming motherboard, it's working fine apart from the reset and shutdown commands. It doesn't restart when exit the bios or choose to restart in the operating system. Shut down also doesn't work, everything works normally until the moment it should turn off. The only way to turn off is by keep pressing power button for a few seconds. What could it be? This would be my first motherboard repair
