System did boot randomly (after changes - I get stabilty but file log is still full of errors)

[interNetWasCoolIn00]

My machine was giving me serious problems after a unfortunate Ctrl+Alt+Del reboot. The PC sometimes didn't boot (freezing before the BIOS image) and, in this case, the cooler over CPU didn't move a muscle. Trying to understand this problem, I've removed all peripherals (reset button, frontal usb, graphic card, etc). Now, running only with cpu/cooler, rams and ssd, the system seems to have achieved a reliable state and boots properly every time a turn the PC on.
PS: briefly, I've tested card memory one by one. Working together, no erro was detected by "memtester 11G 2". CMOS baterry replaced.
QUESTION: I'm using DEBIAN 9. The journalctl and dmesg log accuses some erros. I can't understand them. I want to be sure if the problem is related or not to my motherboard at first. Could someone give a hand about this issue?
System details:

Main Board: TA890GXB HD

RAM: 12 (4+2+4+2) Gb (freq 667 - Kingston)

I havent read the logs yet. but you mentioned "(freezing before the BIOS image)".

If its freezing on the bios, then its nothing to do with the OS, not to say the OS didnt have further issues, but if you reset your bios and re-set all your components and Power-On Self-Test was fine then you may of fixed the initial boot issue.
