Windows 10: why does my pc reboots when playing valorant

my pc reboots when playing valorant. it crashes and boots after 5 minutes of game time. i timed it and its t same every time. i tried different AAA games to stress test if my gpu is the problem but it worked fine. i ran some benchmarking apps to see if my gpu was the problem but it passed the test without crashing.its funny cause valorant is the only game that makes my pc reboot. first it freezes then the screen turns off then my keyboard and mouse turns off but my pc fan and lights are still on. then after the system turns on like nothing happened. i tried changing the power options to high

Valorant Lag after 21H1 Update

So I'm having huge fps drop spikes on VALORANT whenever someone fires a gun and I'm so irritated by that. Before I even update my windows, it doesn't lag at all, I'm getting the usual FPS when I fresh intalled Valorant because I quitted for 2 months after getting an error in the game. And now, I played 1 game on it before I update windows and it doesn't lag, but after I updated it manually, it does this lag on Valorant. My PC becomes smooth but Valorant had fps drop spikes and I can't play it.

 

Whea_Uncorrectable_Error, 12 minutes after opening Valorant.

I happen to have the same issue. This however only started when I updated Valorant to the latest version. Valorant works fine before the update, then when I played it after the update, It also bluescreens with the same WHEA_UNCORRECTABLE_ERROR after about 12-15 minutes of playing.
