Windows 10: Programs crashing one by one until PC finally BSODs

Was using my computer like normal playing games and notice I was getting pop ups for background processes like Razer Synapse and Overwolf saying they were crashing due to a system error. A couple other programs would do this until my PC would blue screen. I ran SFC and it said there were files it could not repair. I ran DISM and it said to "Use the source option to specify location of files...". I am on Windows 10 and wondering if upgrade to Windows 11 could fix the issue. If not, what else can I do. I am not the most tech savvy person so try to explain in simple-ish terms, please.

Pc bsod to bios

Currently replying on iPhone, I’ll give you a proper timeline Step 1) during the program of tuneup plus my pc bsod 3 times but I was finally able to get the info Step 2) Restore point was easy and done quick which now leads to step 3 Step 3) After starting the WDV my pc bsod with the stop code of “System thread exception not handled” following the steps I open command prompt and tried to turn it off which says that nothing was changed, so then after a couple of bsod’s later I manage to go back to my restore point which now leads to a problem I cant seem to fix where when I try to open my pc it says something is wrong with my pin with error code (0x80090016) If needed I do have the tuneup plus info Trying to solve the pin problem if anyone suggestions please inform me.

 

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.
