Windows 10: Upgraded PC brought frequent crashes

Hello everyone! I have recently upgraded my computer. I changed my motherboard, changed CPU from Intel to AMD and even changed the PSU & case. Unfortunately right out of the box, I experienced blue screens and crashes while being sure that everything is sound on the hardware side. To combat that I refreshed my Windows, while still keeping all my files, which has fixed everything for the most part.Today, as I started re-downloading my software, I downloaded steam, and connected my libraries with existing games to it.

I would guess that your GPU is faulty, the crashes that are most frequent seem related to the GPU.

I do have a suggestion, although this suggestion is more often seen with 0x9F crashes where drivers are in an inconsistent state for the OS.
Try to change the powerplan, standard there are following plans

1. Powersaver,
2. Balanced, standard selected,
3. High performance

If you didn't change your power plan, you have balanced selected.
Select High performance and see if it makes a difference.

I suggest the following simple steps:

1. Set the autosave options in MS Office to a low value say 5 minutes.
2. Setup file history to autosave frequently - the shortest period is 5 mins
3. Install Macrium Reflect Free and configure it to do a daily incremental system backup

You should be well covered if you do the above to protect your key files.
