So I have unusual (i think) problem. My new setup that I've build last september has been working fine until now. Few days ago, after I turned off my PC I couldn't turn it back on. I've cleared CMOS, unplugged everything, besides CPU and one stick of RAM and it still wouldn't turn on. I finally got it to work after I pushed the BIOS switch at the back for a few seconds, then unplugged power cable for a 2 minutes. System works flawlessly, no problems at all, but I have to repeat the process each time I turn off PC. It won't turn on unless I push the BIOS and unplug power cable for few seconds... Any idea what's going on?

My specs:
Asus X299-A Prime
Intel i7-7800X
G.Skill Ripjaws V DDR4 32GB (4x8gb)

PSU model?

Have you tried installing a new CMOS battery? I realize that board isn't that old, but this problem sounds very much like one that one of moderators had not too long ago, and surprisingly it turned out to be a bad CMOS battery. I guess it's possible that even a new board could end up having a battery that's been sitting in inventory a while installed by mistake or due to cheapness.

I have exact same problem, however changing the CMOS battery will not help.

Just one correction though, My PC sometime will turn on sometime will not. Clearing CMOS in some instances will help to run it.
Sometimes after I push the power button PC will; not start immediately it will delay for 5-7 sec and then run.
