Random freezing and CRITICAL_PROCESS_DIED even after resetting Windows

I'm running Windows version 21H1 (OS Build 19043.1081). Recently, I tried reinstalling Windows from a USB drive to see if that'd fix the occasional crashes I was getting. It didn't. My computer will usually boot up fine, but after several minutes of use it'll suddenly slow down, freeze, and BSOD. Everytime the same error message is given (CRITICAL_PROCESS_DIED). Sometimes, when my laptop restarts following one of these BSODs, it'll either fail to boot or won't boot correctly.

I've tried doing a sfc /scannow, and I think it helped? But I need to do more testing to confirm this. I've configured my system to create a mini dump after crashing but none are created (there's no minidump folder in my Windows folder). Because reinstalling Windows didn't fix it, I suspect it's an issue with one of my SSDs or RAM modules. But because some of the screws holding my laptop together are stripped, I'll have to take it to a shop if I want to replace or remove anything inside. I want to see if something else could be causing this before I pay for that. It should be noted that I installed my own SSD and RAM shortly after I got this laptop a year ago, and I haven't done this before, so it's possible I messed something up somehow. I really want to fix this because I use this laptop for schoolwork and don't want to lose my work. Thank you.

Edit: the sfc /scannow didn't seem to fix it, my laptop just crashed a few minutes ago.

Check Reliability History for entries covering the problem events.In the search box,bottom left,start typing in reliability and its panel should appear.
The Critical events are red flagged and the ----view tech details---normally give searchable information in lines 1&2.
In the command prompt box,type in----dism /online /cleanup-image /restorehealth----press Enter.
Be patient and note the space immediately before /.
dism needs internet access and uses Microsoft data.
sfc uses data on your computer and if your files have any corruption,then you go around in circles.

Hi joeandmarg0, thanks for the reply. I ran the dism command; let's wait and see if it fixed it. I've also uploaded and shared my reliability history data here: Reliability.XML - Google Drive. All of the critical events from yesterday are either "Windows was not properly shut down" or "Hardware error". The former has no additoinal info, the latter does. The former occured at various times, the latter occured all in the span of two minutes.

Do you get a list when selecting "view tech details"? Lines 1&2 provide data in everyday language and the remainder in string data.
The "Hardware error" is probably linked to your recent replacements and suggest running "Windows Memory Diagnostics" to check on the RAM.
MemTest86 is an alternative
Also run "chkdsk" to see if the ssd has any problems.
Crystalmark" is another alternative.
The stripped screws and holder can be cleaned up by the use of a Tap and Die set,if the fittings and your handyman skills allow.
If not,then another solution is to use a larger screw,but the catch here is if the bigger screw will fit in the existing slot.
The last resort is to use Duct Tape.

Hi, Steve03948.
Which version of your NVIDIA display card driver was?
It might the driver cause BSOD.
I met my computer didn't cold boot and BSOD because NVIDIA display card driver bug in my experience, FYR.

If you are not able to access the hardware because of the damaged screws,then there is nothing more that can be done.
Sometimes the quickest and simplest fix is replacement.
There are various tools available for removing damaged screws,but if you do not feel comfortable doing that,then be sensible and don't attempt it.
Duct tape is an extremely tough waterproof adhesive and is commonly used for plumbing and car paneling temporary repairs,to name a couple.
If used to hold both halves of your laptop together,it is as good as screws,but unsightly.

if there is no memory dump after a bsod then either ram or the hard disk or the cpu is malfunctioning. take the pc to a repair shop for a checkup. they can remove the stripped screws

Actually, I just realized there is a minidump folder in my Windows folder. Which is weird because I don't remember seeing one a few days ago. Anyway, here is the link to the dump files and the HTML report generated by BlueScreenView: Dump files - Google Drive. I should note that I've been attempting to undervolt my processor the past few days, so the dump files might be from those. But the CRITICAL_PROCESS_DIED crashes predated that. Let me know if I should do anything else, thanks.

undo the undervolt and see if you get more bsod
