The H170 got 2 BIOS revisions last year after release and has one for 2016. While its been a while, having a BIOS in the last 6 or so months doesn't constitute abandoned support in my opinion. I'm running a BIOS from 2014 on my board. Last BIOS for it was released in 2015.
If this is a concern to you, have you looked for any beta BIOS? That's said, having the latest BIOS doesn't mean it will be better.
If you are having issues and want help, you need to provide your system specs, OS and the specific issues you are experiencing. If you are running windows 10, issues related to Power Management are related to that OS.. not your hardware, I assure you.
My Asus Z68 has been choking with each new iteration of the OS. Just when I think I have it dialed in again, it won't go to sleep, doesn't resume from standby, or doesn't find my RAID array on boot... Next update, everything works.. 3 weeks later and I'm ready to throw it out the window.
Asus is your usual brand. It was mine too, for 13 years, but they will probably never see another dollar of my hard earned money again. After my experiences and dealing directly with their Tech Support. The few times I actually needed them they didn't come through, don't stand behind their product and left me out in the cold. No sympathy from me... sorry. All mainboard manufacturers have issues. Sure you'll have less if you stick with the bigger outfits, but none are perfect.
So lets not turn this into a bashing thread. If you want help, let us know what you have and what you are dealing with. We can't solve everything, but there are a lot of good people here who are happy to try and help.
