Windows 10: My PC crashes into a BSOD when I play Library of Ruina for a short amount of time. The stop...

Last time it crashed while playing, the stop code was MACHINE_CHECK_EXCEPTION and I didn't know how to fix both of them, so I used the command prompt, ran it as an administrator and typed 'sfc /scannow'. It kind of helped a bit, but there's a corrupted recycle bin in my G: driver, but that's not a problem for me. It did work and I could play the game for a little longer, but then it crashed into another BSOD with the stop code 'SYSTEM_SERVICE_EXCEPTION'. This only happens to that one specific game. I'm very confused and quite annoyed at this, seeing as I can't play the game I like consistently

:)

 

all games crash!

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

PC crashes on playing media

Whenever I play a video, either from hard disk or on YouTube the PC crashes after a while. It gave BSOD once with the error video tdr failure atikmpag.sys. At other times it just gives a long beep sound with glitches on the screen, and hangs there until I hard restart it.
I did a memory diagnosis, but there were no errors.

AMD Ryzen 2400g processor

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?
