Reliability history shows a hardware failure on 2/28. Report copied below. No other hardware failures reported. Only indication of this problem is the "windows didn't shut down properly" report every day.
Interestingly, every day leading up to when I got my new gpu shows dmw.exe stopped working. Once the new card is installed, this error goes away. No clue what that means.

The PSU is a Corsair cx600. I've reinstalled the AMD drivers several times using Display Driver Uninstaller to clean the old ones a couple times. I will try the TDR fix (hopefully the instructions for Windows 7/8 work for Windows 10. I can't find any specifically for 10.) tonight. I have Open Hardware Monitor up during use and the card is not overheating and the fans are working as intended. I'm also skeptical of a load related problem, because the load on the card makes no difference to the symptoms. Whether I'm playing tomb raider at max settings of just browsing the internet, the computer still crashes after 10 minutes. Also if it was a load issue I feel like I would be able to reproduce the problem after the first crash, but once it crashes the computer works fine the rest of the day.
