Z170X-UD5 with Intel 750 NVME boots normally every second time

Hi

when I put together my new comp, Z170X-UD5 with Intel SSD 750 PCiE, cold boot went every time to bios, and I had to reset boot priority and did a warn restart and then booted normally to windows 10. I upgraded bios to F5f beta, and now this problem has gone, but very funny strange thing is happening. I do a cold boot, and when boot comes over Bios check the computer just shuts down itself. and then I do again cold start, and it normally boots into windows 10. OK, then I shut down again and wait few minutes, and then do a cold start again, and the same story, computer shuts down itself after checking bios. and then again cold start and everything goes OK. and so on and so on.. any suggestions? and I also recomend Gigabyte that they make a news bios with this error checked and solved.

Did you do cmos clear after you updated it?

Did you do cmos clear after you updated it?

I did, the same situation, must start the system twice, first time shuts down itself after bios checking, second time starts normally

now I am waiting Gigabyte to launch new Bios, I hope this will work with new version
