Question BSOD that sometimes lets me into my PC but most of the time doesn't...

[Hilly541]

Hi, first time poster on here.

Been racking my brain for the past few days trying to solve a fairly recent BSOD that won't go away. Some background to the issue:

My PC was working perfectly fine with no issues at all until I recently uninstalled Avast and switched to Defender as I felt as if I didn't need Avast anymore (uninstalled Avast through programs and features and didn't realise there was a specific tool you could use for it until after). I let Defender do an intelligence update and then a Windows update shortly followed, this update reversed itself around halfway through (rough estimate as I wasn't really looking), my PC shut down, and since, I've been having a SYSTEM THREAD EXCEPTION NOT HANDLED 0x000007E BSOD plague my startup.

I've done multiple system restores from a restore point that was automatically made when my PC booted after one of the BSOD's took place, tried to diagnose/fix the issue using the usual chkdsk, DISM checks, sfc, Windows Memory Diagnostic etc. to no avail. I checked the crashdump in WhoCrashed and it said that ntoskrnl.exe was causing the issue (which as far as I understand is very generic). The system restore that I had to fall back on has since somehow disappeared. So I'm relying on Windows to boot sometimes (which it still does occasionally) to use my PC. Hoping that someone a bit more versed in diagnosing/fixing these issues can help!

Just realised I may have posted this in the wrong section also, apologies if so.

Could you post your system specs.
Sometimes, uninstalling an antivirus could corrupt a disk or OS.
Have you tried the Avast uninstall tool, it could be used even after uninstalling the program.

If the OS is corrupted, it can be fixed by re-installing Windows using an installation media (USB disk) and selecting to keep "All apps and settings"

How old is your system disk?

System disk is as old as the PC is. I'd be inclined to say late 2015/early 2016.

Have also used Avast Uninstall tool, might have been undone though as I had to go back to restore point after doing it due to another BSOD.

Your system is not that old, but to keep it working properly, it needs maintenance.

The minidumps do not contain much data. They all have the same bug check 0x1000007E pointing to the same file ntkrnlmp.exe. But it did not catch what was causing the issue.
That code could be related to missing important drivers or updates...also it could be corrupted system files or failing disk.

Could you updated BIOS and Windows 10 the latest versions available and also your hardware drivers.

I would also consider upgrading the hard disk to a SATA SSD before it fails.
