Windows 10: My Windows 11 PC keeps crashing without a BSOD

I keep having crashes on my W11 PC that don't give a blue screen error. I found two events on Event Viewer, but I am unsure of what to do with the information it has given me:The RstMwService service terminated with the following error: %%2684420176The VSSrv service failed to start due to the following error: The system cannot find the file specified.My specs are:Windows 11 Homei7 13700kMAG Z790 TOMAHAWK WIFI MS-7D91G.Skill Ripjaws S5 Series 32GB 2 x 16GB DDR5 6000EV

Windows 11 constantly crashes without BSOD

After updating Windows 10 to Windows 11, my PC keeps crashing without BSOD. It takes between 15 minutes to several hours after start-up to crash. When the crash occurs, the PC first freezes for a few seconds, after which it starts rebooting. These crashes have never occurred before the update.

Attached here is the minidump file produced by the latest crash:

My hardware:

• Motherboard - X570 Asrock Phantom Gaming 4 rev 1.05
  
• CPU - AMD Ryzen 7 5800x
  
• GPU - AMD Gigabyte RX 6700xt
  
• RAM - Teamgroup Vullcan Z 2x16 Gb
  

I have tried:

• Reinstalling the GPU driver
  
• Running SFC /Scannow
  
• Running DISM/Online/Cleanup-Image/RestoreHealth
  
• Resetting Windows with 'Keep my files' option
  

None of these have helped alleviate the crashes.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

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?
