@tm0418 The link worked fine. The crash dump points to the Nvidia driver, but the driver is only the first among several possible culprits. Did you in fact go through the DDU process to remove the old graphics driver, as described here?

If you did not, if you merely updated the driver or uninstalled using the standard Windows method or something else, please DDU and reinstall the driver now, exactly as the guide describes.
If that doesn't help, or you already DDU'd the driver, please run a repair install of Windows, as described here:

This allows you to keep all your data, but if you get to step 13 and are NOT asked whether you want to keep your personal files and apps, back out and start over.
Finally, do you have or have access to another graphics card you could test with? It would be helpful to see whether the system is stable with a different GPU. Your power supply should support anything out there, literally, as long as it has enough power cables. But a lower-end or older card would be fine—this isn't about performance, just system stability.
