[SOLVED] BSOD - Cant boot normal drive, can't even re-install windows from usb

Started getting intermittent bluescreens a few weeks ago. They were around a week apart usually, and would reboot fine first time. I attributed it to the fact that I only had 1x8gb ram stick in while I was running a ryzen 5 2600 setup. BSOD would usually be when I had a few ram-heavy applications going.

Last week it started failing to boot properly at all. Would start to load windows automatic repair and then bsod again. It never gets past this stage now. Getting a few stopcodes, but the most common were:
MACHINE CHECK EXCEPTION
IQRL NOT LESS OR EQUAL
KMODE EXCEPTION NOT HANDLED

Googling the problem led me to believe it might be a bad ram stick - but I tried a fresh one, and still the same bsod pattern.

My hardware:
Gigabyte a320m-s2h (3 months old)
Ryzen 5 2600 (3 months old)
Team Group Elite ddr4 ram 1x8gb 2400mhz ted48g2400c1601 (Brand new)
Silverstone ET650B power supply
Sapphire Radeon R9 270x (a few years old)

When trying to strip down the pc to its essentials and boot using onboard graphics rather than gpu - the onboard graphics wasn't listed as an option in the bios. Am I right in assuming this is a sign that the CPU might be to culprit?

If you can get to your bios then you could try and do a re-format for win 10 see if that helps would rule out software side.Do you know what sort of temps you were getting when you overclocked?
Haven't seen mention of using Intel's diagnostics on an AMD CPU; that's certainly new to me. And overclocking isn't supported on the A320 chipset. Temperature is always worth verifying.

What BIOS is the motherboard on? F20 is required for the Ryzen 5 2600. There's only one newer BIOS (F23). It may be worth considering if the system remains unstable for whatever reason.

The RAM you've listed is compatible with the motherboard so we can rule out a compatibility issue: https://www.gigabyte.com/Motherboard/GA-A320M-S2H-rev-1x#support-doc
What it doesn't rule out is faulty RAM. Have you used Memtest to check for errors? If not then it's worth considering to rule out an actual RAM stick issue.

If you haven't already, then configure Windows for crash dumps. Then upload and link them here or a new thread. There are a few forum members who know how to analyse them. Often BSODs are RAM or driver issues. Can you get into safe mode at all? That may help with narrowing down possibilities.

obakasama is right in what he says .try also testing your ram like obakasama mentioned,what windows are you on? also if you can get into safe mode you can try re-installing your drivers

Yes, i have overclocked the cpu, but not by much since it only came with the stock wraith cooler. From 3.4ghz to 3.7ghz. Was getting temps around 75 degrees celcius when stress testing with AMD overdrive software.

Cant boot into safe mode, as it will bsod before it gets that far. Yesterday i reseated everything and tried a new ram stick, different slots, and still got the same result.

I'm using windows 10.
 
The Ryzen + CPUs should be better overclockers as rigger922 mentions.

Are you getting these BSODs while it's overclocked?

How are you actually overclocking? (AMD Overdrive is used with the previous AMD CPUs and not really designed for Ryzen as far as I'm aware.)

Have you removed the overclock to go back to stock settings to see if BSODs still occur? It could well be an unstable overclock causing these issues. Every piece of silicon acts differently.

I have literally the same problem
My specs:
Asrock z390 extreme4
Intel 9700k stock clock
16gb DDR4 3200 gskill ripjaws
My pc crash suddenly while playing Path of Exile and after cant boot, cant boot from usb, cant get to safemode always boot or bsod before it goes forward...
