I already tested over 12 hours of memtest86+ without errors, hours of Prime95 under Linux and Windows, but when I decide to to make real use of the computer (browser, install other stuff), suddenly crashes.
CPU won't overheat, it's cooled by a beefy cooler, it barely hits 50°C in Prime95.
System is running Windows 10 Professional 64-bit version 1903 build 18362.449 I believe.
The recent crash dump is a watchdog error (0x133) and should be fixed by updating the graphics driver.
Please update the NVidia driver. The best way to do this is to uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from your Graphics card manufacturer or from the NVidia website. When you do this be sure the "clean install" box is checked and only install the Graphics driver and the PhysX driver.
The older crashes recorded in msinfo32 are the hardware BSOD errors but as there are no crash dump files it is pure speculation what might have caused them. It is best to wait until you get some new 0x124 BSOD crashes and post new log files.
