What is causing my computer to BSOD at random times?

I have a custom built gaming PC that has recently been blue screening randomly and it seems completely unprompted. It happens when I'm in the middle of a game, or when I'm working on a Word document with Spotify playing, or when I'm browsing google chrome with nothing else open. I don't know what could be causing it.

The error I get is always "KMODE_EXCEPTION_NOT_HANDLED"

I recently had an issue where my computer would BSOD with the same error every time I woke it up from sleep mode. I got a warranty replacement for my RAM and that fixed that issue. These BSODs seem to be caused by something else. This also means that I find it highly unlikely that there's something wrong with my RAM.

Here is a link to the dump files I've gathered so far. I will add more as my computer continues to crash. It happens once every few hours, it seems.

Does anybody know what could be causing this issue? Do the dump files point to anything specifically that could be causing the crashes?

Thank you

    Hello All,

    My laptop CPU does not support Intel Control-flow Enforcement Technology (CET) - I don't know what percentage of CPUs currently in use support this feature. Security in depth is a "good thing", but stopping malware being deployed to a system is always the better option. Since I sleep well without CET, I am not reluctant to suggest disabling it as a work-around for irritating problems.

    I think that the Windows kernel naming prefix "Hv" refers to routines related to "hives" (where registry information is stored); I believe that "Hvl" (Hypervisor Library?) is the prefix used for hypervisor related functions.

    There are a few hits when searching for crashes where an exception occurs in the routine HvpGetCellPaged (as is the case for the 1st January crash) but, as usual, there is no information about the cause. I would regard the crash as "unexplained" and not necessarily hardware related.

    This is not a BSOD due to software fault... it is a BSOD due to hardware fault.

    This really now looks like a solid hardware defect on RAM, or RAM misconfiguration on mainboard. It could also be the CPU, and third, the mainboard. The most likely is the RAM, not placed in the exact right combination proposed by the mainboard manual, or a defect.

    @edit: it can also happen naturally under extreme stress but must never happen when not under heavy stress.

    Uhoh. That isn't good. A hyper-V error.

    A hyper-V memory error essentially. That is really not good.

    You have the latest bios update? and the latest chipset drivers?

    Hi Alex,

    You should not use the bcdedit solution unless you are forced to. This is an alternative solution branch where you help the nameless ring0 shellcode by disabling your own hardware security. This would essentially resolve the shellcode-related problem as an alternative way.

    If the Core Isolation way works, it is much better, because you do not have to disable your own security to help a dubious shellcode. Since we are not 100% sure it is patchguard the way not disabling your security would much be preferred.

    Also, it's either Core Isolation OR disabling the Intel CET. You can't take both approaches!

    Garys way is a last-resort solution, and/or an option when you are a competitive gamer / doing hardcore eSports and you absolutely can't live together with the Core Isolation, because Core Isolation has a strong tendency of fending off Anti-Cheat software using drivers that mess with the kernel in an inproper way.

    Wow, two sources of BSODs is just exceptionally unlucky. I will have a short look at the new dump.
