Hey everyone, I'm dealing with a frustrating issue on my Windows 11 PC. It keeps crashing with a blue screen every few minutes, showing the error code 'Kmode Exception Not Handled.' Initially, the PC wasn't bootable at all, but after installing a new M.2 SSD and doing a fresh Windows install from a USB, it starts up now. However, I still get the blue screen errors after a brief period of use, and sometimes it shows a 'DPC Watchdog violation' message too. Any insights or solutions would be greatly appreciated!

It sounds like there might be an issue with your CPU, especially since you've got a Matisse CPU and several dumps indicate crashes on the same core. Have you run any tests to check for faulty memory? Running MemTest86 is a good start if you haven't already tried that. Also, if you've swapped out your SSD, that's a good step toward ruling out hardware problems. Just ensure all your components are seated properly too!
First off, make sure you've backed up your data before changing any settings. To diagnose those blue screen errors, you'll want to check for any crash dump files. If you can boot into Windows or Safe Mode, look in C:WindowsMinidump for any .dmp files. If you find any, zip the folder and upload it to a file-sharing site like MediaFire or Catbox. If you haven't set up your system to create minidumps, follow a guide on how to adjust those settings as multiple dumps can help identify the issue better.
Yeah, I've run MemTest86, but I haven’t found anything unusual. The SSD swap was a thoughtful move to troubleshoot.
