x370 prime pro - doesn't boot every third or fourth time

[Bayberry]

Hello,

I built a new pc and have one problem, every third or fourth time windows doesn't boot because ssd is not detected. I tried to change port on motherboard and also I changed data sata cable but I still have problem. I didn't overclock anything. Does anyone know any possible solution? Everything other with PC is ok.

I would suspect that your SSD is getting flaky. That MX100 isn't made anymore; how old is this drive? And have you look at the SMART status (using, for example, Crystal Disk Info)?
And, when this happens, does it always happen on a warm boot? Or does it happen sometimes on a cold boot?

That ssd is the only one component what I keep from old pc but it worked very well and never had problem.

There is s.m.a.r.t log from crucial software;

OK ... the SMART log doesn't seem to indicate any issues at all and only 2% of the lifetime used.
You've flashed the BIOS, changed ports, changed cables, etc so that can't be it. That said, perhaps it possible that there's a compatibility issue between the drive and the chipset? That would surprise me but it's not out of the realm of possibility. Ha
Questions: is there a firmware update for the drive? Do you have it set for AHCI mode or RAID in the BIOS? (If not using Intel RAID, you should have it set for AHCI).
What about the power supply? Have you tried plugging the cables into a different port? Using a different cable set?

[Bayberry]

It is set to ACHI by default in bios. Latest ssd firmware is installed, but it's old firmware because that drive is old about 3 years like you said. Only thing what I didn't try is that PSU slots and cable, that is next what I will do. And that happens on cold boot also, for example when I come to home from work, about every third or fourth time like I described, not every time.

[DevBiker]

Cold boot also? So it happens on a warm boot as well as a cold boot? Or just a cold boot?
What happens if you just put the computer to sleep and resume?

[Bayberry]

It happens on cold boot for sure, but actually I am not sure 100% for warm boot, because I can't remember situation when I shut down pc and turnet it on in short period of time. But it never happens after restart or after sleep, problem is only on power on.
