[SOLVED] ASROCK b450m Kernel security check failure.. please help me

[Road2Seven]

New pc build has been working great for little over 2 months. The pc went to sleep yesterday afternoon for like 4 hours, tried to wake it back up and nothing but black screen, 34” LG monitor not responding. I forced restart and the BSOD showed up “Kernal Security Check Failure”. I couldn’t believe it.. I shut it all down and let it sit overnight to see if it would wake up from a cold start. Nothing.. today I have troubleshooted this all day. Checked and ran MemTest86 with 4 passes, all results no errors.. i thought it was the ram. I went back through and checked the NVme and SSD and still nothing. Updated the Asrock b450m steel legend bios to 2.50 going through each bios update one by one from 2.10. I didn’t update since everything was working good except the RGB app was little glitchy.. I never ran a dump file and decided to wipe the NVme m.2 boot drive to reinstall a new fresh version of windows 10. Nothing and still getting blue screen with same error.. I’ve tried multiple usb drives. I have removed the graphics card and used the on board display port, no change. I’m an totally clueless and new to this. Pretty frustrated that I can’t install a new windows 10 from boot drive and this pesky blue screen won’t go away even after doing a secure erase of the NVme m.2 which I now regret..

Please help me.. I do not know what to do.. can an older version of Windows work? Is there a way to access installed drivers through the asrock b450m UEFI. I couldn’t get to Windows at all, so no safe mode.. starting to feel like a major problem.. could the RGB LED Asrock app caused this.. please anyone, I need some help.

is ram running at 2933 or 3000? 2933 is default speed for Ryzen ram sticks running at 3000.

Just thought I check as that can be 1 reason

Could try making a new USB installer as if you still getting a BSOD on a clean drive, it could be the installer as you can only be running in ram at that stage

could try running memtest86 on each of your ram sticks, one stick at a time, up to 4 passes. Only error count you want is 0, any higher could be cause of the BSOD. Remove/replace ram sticks with errors.

Do you have latest bios for motherboard?
Is ram on motherboard QVL list?

Do you have latest bios for motherboard?

The ram is set with XMP profile 1.0 which is 3000, there are 2 profiles for these sticks. The second profile is 2666. Or should I set them at AUTO?

I purchased a new USB drive last night and download a new version of Windows 10 and will keep it as a boot drive as needed, still same result.

I have updated the latest bios, the mother came with 2.10 and the sticker on the board also states this.. I kept 2.10 because everything was working as expected. A few weeks ago I had updated to 2.50 because new bios was available, but then the Asrock Polychrome RGB wouldn’t load and the lights would stay on after a complete shut down.. That app continued to crash.. I flashed back to 2.10 bios and everything was stable again with the Polychrome app after an uninstall and reinstall.. Currently the board is updated to 2.50 from 2.12A, 2.30, 2.40. Each done separately...

The QVL list shows Adata Ram stock and the product number but I don’t see D41 anywhere. I had saw a PC Build using these sticks with the B450M steel legend, AM4 and therefore went ahead after tons of research with this set. XPG Spectrix D41 3000mhz 8GB each.. I did run the MemTest86 on both stick with no errors.. I can try running one stick at a time on A2 or B2, or should I use A1 and B1?

I also quickly ordered new ram stick that were on the QVL list (HyperX predator 2x8GB 3200mhz (HX432C16PB3AK2/16)) they will be here today..

I will run another MemTest86 this morning with each stick and see the results.

I’m just surprised that wiping the NVme m.2 didn’t work, obviously there is either something on the board memory or elsewhere causing the blue screen even after everything was removed..

Another 8 passes on ram sticks. No errors.. I have put in a RMA with Newegg.. motherboard could be the issue.. 1 day before 30 days return policy..

What’s another motherboard that someone can recommend.. needs something reliable and has power. User friendly UEFI and bios.. needs to be compatible with Ryzen 5 2600.

did you try stripping it down to bare basics, taking motherboard out of case, only have 1 stick of ram, 1 drive attached, gpu only (since you have to)

i should have reads your op and seen you had already tested memtest. I wasn't the best yesterday...

have you checked CPU?

I don't like blaming parts until I am sure its not something else.
