Overclocking side effects?

[Kevo05s]

So, a year ago I built my rig with an i7 6700K and an MSi Z170A Gaming Pro Carbon. I was able to dial in an overclock to 4.7GHz 1.38V, it was 100% stable and I was happy with it. 6 months later, I plug something in the USB 3.1 Type A, and it literally corrupted windows, after 6 windows reinstall I can confirm that the port is the cause of the BSODs and windows corruption.

Then I bought an ASRock Z270 Extreme4 because the MSI had a broken port AND I needed more SATA ports. Plus I thought the ASRock looked better.

I tried dialing my OC in the new board, it BSODed for bad OC, I just brought it back to stock and was happy about it. 3 days ago I decided to give overclocking a try, and I got it stable again at 4.7GHz with 1.385V this time. It has been stable since (I gamed all day yesterday and it never crashed, temps were fine). Today, I was browsing youtube, suddenly all my screens go black, but sound keeps playing (dedicated GPU and dedicated sound card), comes back with a sound of USB unplugged, and now none of my USB ports are working in Windows, I reboot, I can get into the bios, both keyboard and mouse are working, try to boot, gets to the login screen, none of my USB works, nor my PS/2 keyboard. I try to reboot again, BSOD: unable to reach boot device... I reboot again, the raid controller says all my drives are fine, and I can get into the BIOS again and my USB devices work, but I can't boot anymore...

 

Are my problem caused by my overclocks being too hard on the board voltage wise? Or am I just bad-lucky?

bad luck, try to add more voltage on your CPU, might fix.  i had an issue with windows just not booting up (couldnt find bootloader) because i installed a different GPU

Your issue is called "MSi"

Try resetting to stock clocks and see what happens.

CPUs degrade slightly over time, so you might need to either pump a bit more voltage, or lower the clockspeed, after several years of use. however, this seems too soon for that to be an issue. maybe the board just has worse power delivery (less phases, more ripple, etc.)

It wasn't my first board, but I don't know how I feel about them, they feel cheap and their drivers are subpar for the audio chipset, but they deliver some solid OC stability and a great customer support in Canada, plus now I have a dedicated sound card...

Also, I'm having issues with the ASRock one now... So that's why I'm starting to think I'm the problem

The MSI had 7 phases, while the ASRock has 10... the power supply is the same (EVGA 650GQ, not the best, but does a good job)

Hm...

Strange.

I reset my clocks to stock, will use it for a while, then, if the crash doesn't happen, I'll start over with my overclock and see what will happen
