[SOLVED] Computer crashes with no BSOD or other error messages. FIX: replaced the old dying PSU with a new one.

Okay, I've tested every combination of my two RAM sticks with my four slots. Here are the results.

Stick #Slot #Approximate time before crash
122 hrs
143 hrs
111 hr
136 hrs
228 hrs
241.5 hrs
212.5 hrs
232 hrs
 
I think we can conclude that the turning off has to do with something else other than the RAM and slots. Either the motherboard is faulty or PSU. I think your tests with a different surge protector and different power socket will be interesting too. I have known of problems from the external power leads and connections.
 
The different surge protector and different power socket did not seem to change anything unfortunately. I still had the computer turn off and back on exactly the same as it's been doing. Did the multimeter test not eliminate the PSU as possibly being faulty? I figured since all the voltages I got were normal, that meant my PSU is perfectly fine. Is there a way to determine if the motherboard is faulty without buying a new motherboard?

It could be the PSU is slowly dying... Therefore, it loses power whenever it "prefers".

Haha that's what I like to hear, my computer parts choosing to do their own thing. I don't have another PSU lying around, or even another desktop I could "borrow" from. I guess I'll buy a new one to try and make sure I can return it if it doesn't fix the issue.
 
New development, I did finally get a blue screen. System Service Exception was the stop code. Any advice for getting the collection app to work? I've tried again today with no success.
 
Please can you try to copy the dump files to a folder on OneDrive and share them with a link.
 
Microsoft Defender is the only AV I am using.

Dump Files Here is the link to the dump files from the BSOD I got last night, and the two additional crashes I had this morning shortly after I turned on my computer. The BSOD I had this morning had the Kernel Security Check Failure error message.

Not sure if this is related, but I have had this webpage crash in Firefox a couple times this morning when trying to send this response.
 
One of your dump files does give a clue:

Code: 
Debug session time: Thu Aug 20 02:26:45.029 2020 (UTC + 1:00)
Loading Dump File: 082020-7093-01.dmp
System Uptime: 0 days 0:00:17.646
BugCheck Info: INTERNAL_POWER_ERROR (a0)
Bugcheck code 000000a0
Arguments:
Arg1: 000000000000010e, The disk subsystem returned corrupt data while reading from the hibernation file.
Arg2: 000000000000000a
Arg3: 000000000000ac4d, Incorrect checksum
Arg4: 0000000000000d79, Previous disk read's checksum
BUGCHECK_STR:  0xa0_10e
Probably caused by: ntkrnlmp.exe ( nt!PopHiberChecksumHiberFileData+1083c )
FAILURE_BUCKET_ID:  0xa0_10e_nt!PopHiberChecksumHiberFileData

It looks like corrupted data was retrieved from the hibernation file. It's a power error which seems consistent with the direction we have been taking in the troubleshooting.

Thanks for taking a look! I'm guessing my next step is to get a new power supply then?

Well, in my mind it's not conclusive - the motherboard could still be faulty and causing an interruption on the power supply to the disk system. Unfortunately there is no way of telling, as far as I know, and so you are going to have to test with a replacement. Maybe you can get a PSU on the understanding that you can return it if it does not fix the problem. Hopefully @xilolee will also add advice.
 
That error shown by philc43 seems related to the hibernation file.
I'd disable the hibernation altogether; run this command from an elevated command prompt (i.e., run it as administrator)
Code: 
Powercfg /h off
Then reboot, and cross fingers and hair.
 
I have had three more crashes since trying to disable the hibernation. Dump Files Here is the folder with the new dump files added to it. I have seen two new error messages on the BSOD, PFN List Corrupt and KMode Exception Not Handled.
 
And now another BSOD, Page Fault in Nonpaged Area is the new error code. I have turned off my computer for now, I can get back on to add the new dump file to the folder if you need it.
 
I booted into safe mode to do some digging around, and had yet another BSOD with the error message System Service Exception. Would doing a fresh installation of windows help anything?
 
No point doing a fresh installation with a PC that is misbehaving like this - the fact that it is happening in Safe Mode is confirmation it is a hardware problem.
 
Got it, thanks philc43. I plan to go buy a new PSU today and see what happens. When I tried disabling the hibernation per xilolee's suggestion, I got a BSOD after I initiated the restart but before it shut down.
