BSOD's on a 3 month-old system, already re-installed Windows once.

I've had this computer for a little over 3 months now, and about 2 or 3 weeks ago I started getting a ton of bluescreens, at the start I was able to get into Windows after the computer restarted, but giving me very little time before another bluescreen happened, and eventually I was stuck in a BSOD loop where my computer would bluescreen before the Windows 10 log-in screen loaded with the error "CRITICAL_PROCESS_DIED".

Nothing in the Windows 10 recovery/repair screen worked, every CMD command came back with "Windows Resource Protection could not perform the requested operation", or simply telling me that whatever command I wrote wasn't recognized --The only command that worked was the command to bring up Windows Memory Diagnostic(which came back with 0 errors by the way).

I couldn't even re-install Windows, it simply came back with "We could not reset this PC." or something very similar.

That was 2 weeks ago, and now the bluescreens are happening again after a re-install and wipe of my drives, and games(specifically only World of Warcraft) is crashing after being open for 30 minutes to 1 hour.

I contacted Blizzard Support about that, mentioned the BSOD's and they said "I'm sorry to hear about your crashes, and it's pretty clear that there's something going on with your hard disk or memory, which is only reinforced by the crash dump you provided, as it states a memory location and claims it can't be read."

I would be eternally greatful if anyone is able to help me with this issue.

Here are the things I've tried, but probably non if it matters as Blizzard Support(I did tell them about the BSOD's) seem to be very certain it's either a drive or RAM issue.

Unlike the last time I started getting BSOD's my computer isn't unusable, and I'm not constantly getting BSOD's, it has 'only' happened twice so far.

I have right-clicked my main drive and done the "Error Checking" scan, I've done a "chkdsk" and ran a "sfc /scannow" scan, all of which came back with no errors and the need to repair no files.

I've checked my main drive(Samsung 960 PRO) read/write speed with Samsung Magician, and the results are a little under what is advertised, "Drive condition" shows up as "GOOD" and it has the latest firmware.

Windows Update has no updates for me to install.

I've ran numerous virus scans, all of which come back clean.

Windows Memeory Diagnostic came back with 0 errors(I ran the Standard scan, not Basic or Extended).

I have updated my BIOS(I did that the last time this happened when my computer became unusable, no new BIOS update has been released since).

I have disabled Intel Turbo Boost Max Technology 3.0 and I haven't used MSI Afterburner since the last BSOD I got in case any overclocking was a contributor to the bluescreens.

I have extensively checked my drives for folders, files, programs, etc. that I do not need and have deleted anything I can. The only things I found that could be deleted were temp files, log files(I didn't delete the BSOD minidumps) and some random folders in AppData that were left over from some uninstalled games.

I have checked some BIOS settings to see if there was anything disabled/enabled that should be enabled/disabled.

I do not use Java or Adobe, in case that is of interest.

I have checked all my drivers, everything is up-to-date, except that I'm unsure if every firmware on my motherboard(WiFi, Bluetooth, etc) is updated because as described below, the driver install process confuses me, and I also don't know how to check current driver versions for those modules of the motherboard.

---------------

Another thing that may be useful information is that my built-in WiFi adapter in my ASUS x299 E-Gaming motherboard has ever since I got the motherboard been randomly disconnecting itself from the internet, or turning itself off.
I downloaded the latest driver and simply ran the installer exe inside the folder called "W10"(under W7), the installer showed up for 1-2 seconds in my startbar, went away, my WiFi was disconnected and turned off, then it turned back on after 3-4 seconds and I had to manually connect back to the internet.
I'm unsure if it actually updated or not, I have to contact ASUS support to ask if I did something wrong, or if they designed the driver update process to be like that.

you should also provide access to the actual memory dump files. the automated debugging does not provide the proper info to determine the actual cause of the problem.

both case indicate a bad memory address used by a driver.
often in cases with a bad stack pointer you will find overheating, overclocking, or power fluctuations to the cpu as a root cause.

here are some things you might do:

run malwarebytes scan, (removes malware that infects storage drivers)
run dism.exe /online /cleanup-image /restorehealth (remove hacked drivers)

remove any cpu and gpu overclock drivers (gpu overclock can cause a brown out to the cpu in certain cases)

sometimes you need to underclock a factory overclocked GPU if your system overheats while...

Can you follow option one on the following link - here
and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD

that creates a file in c windows/minidump after the next BSOD
copy that file to documents
upload the copy from documents to a cloud server and share the link here and someone with right software to read them will help you fix it :)

always handy the WiFi doesn't show who actually makes the chip. it could be realtek or Intel - https://www.asus.com/au/Motherboards/ROG-STRIX-X299-E-GAMING/specifications/

what are specs of PC? Is WOW on the SSD?

sometimes you need to underclock a factory overclocked GPU if your system overheats while playing a game. (crank up the GPU fan speeds if you can)

provide info on the PSU, make sure the GPU is getting proper power. check gpu power cables and make sure they are not on a shared power connection (splitter)

monitor temps of the system, crank up the fan.


since one of the failures was in the file system you should update the BIOS if it is out of date, then update the cpu chipset drivers and the motherboard sata 3 drivers from the motherboard vendors website.

if you have a ssd you should run crystal disk info and check the drives firmware version and see if you need a update to the firmware. for hdd you can check the drive health (not likely problem in this case)

consider changing the sata port and controller that the drive drive data cable is connected to.
often windows will update the slower sata driver directly supported by the cpu but you have to update the sata 3 driver from your motherboard vendor. This means there tends to be less bugs in the slower cpu supported driver.

if you are running any special drivers for your drive you should update them or remove them.
(some people use defrag driver, and 3 party tools)

most of these problems can be identified if you provide the actual memory dump file.

start with making sure the ram is installed. make a bootable memtest usb stick run it overnight see if the ram has any isssues. if the ram passes download hardware info run it see if your power supply not holding within atx spec. also if you have an intel cpu run the intel cpu tests make sure the cpu cache is fine. if it not the cpu it could be bad vrm under load.
