Common apps throwing the tpm-wmi 1796 error were the BattleEye anti-cheat software and Terraria game. From the trend, it indicates that games and gaming software could be behind the PC crash.

Games don’t usually crash PCs but if you have lower-end hardware, then the crashing could happen frequently. Further, anti-cheat software usually has compatibility issues with most hardware and your antivirus.

You can either upgrade your graphics card or optimize your PC for gaming and see if there are any changes.
