Windows 10: BSOD when I was away from my PC. What could be causing it?

Hi,


I got the following error when I checked the dump files following a BSOD when the computer restarted. I was away at the time.

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?

 

BSOD Hardware Caused???

they do weird things like that, which all seem like something else is failing.
One of the worst things to diagnose, they seem to only quit when they want to.

Memtest is a good next step, if you rule out RAM and Power Supply make sure you disconnect all unnecessary peripherals and try to start the system with as little hardware as possible, if it works then, you can narrow down the culprit by trial and error.

the follow was taken from some website:

It's very difficult to determine if a failure is caused by the CPU because many other components can cause the same symptom when they fail.

1. System fails to boot
2. System re-boots intermittently
3. General Protection Fault
4. Illegal Operation
5. Stop Error, or BSoD (Blue Screen OfDeath)

Actually, CPUs rarely fail, and about the only way to determine if the CPU is causing the failure is to swap it out with a known working CPU of the same type and speed. Since this is difficult, the best bet is to first rule out every other possibility.

Before suspecting the CPU, rule out all the possibilities listed below.

1. The Operating System
2. A peripheral port device
3. A bad memory module
4. The hard disk drive
5. The power supply
6. The motherboard

If you have ruled out out all the other possibilities, investigate the items listed below.

1. Overheating
2. A short circuit
3. ESD

 

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.
