I have a gigabyte z370 motherboard with the 8700k. This issue has been going on randomly for a long time now. Most of the time it does not happen. At time, after pressing the power switch on the case, it would boot into bios only after pressing the reset switch once or a couple of times. Once it is able to boot into bios it would start normally into windows. Everything function normally including stressing and gaming. Any insight into what is causing this would be appreciated.
