My PC freezes since 1-2 weeks if I have secure boot enabled
I hope this is the right subreddit for my topic. So I was playing valorant normal these past couple of weeks. But since couple days if not more than one week something strange happened. I logged in into my valorant account to play like any other day. Suddenly I get the error that I need to activate my secure boot setting in the BIOS and my TPM 2.0 as Vanguard demanded both. This was very strange to me because I activated both of it so I could play the past weeks. I was confused but nonetheless I went to my bios settings and activated secure boot and my Intel PTT as I did weeks ago to play valorant. So I changed my settings again and startet valorant and all of a sudden I have a blue screen with an error. This is the first time ever that I had a blue screen so I was confused and turned my PC off by pressing the button on my PC and tried again but now I got a blue screen again. I was confused again and got another valorant punished for leaving the game (which was not my fault). I went to youtube to relax but here also my PC froze after couple of minutes. I set my secure boot and my Intel PTT settings in my BIOS back and since then my freezings have stopped. I did some experiments and I found out that if I have secure boot activated, doesnt matter if I have valorant/vanguard installed or not, my PC always freezes after like 2-5 Min. I really dont know what to do. At the moment I cant play Valorant due to this problem which only occured since like max 1-2 weeks. I tried everything also with the help of ChatGPT but nothing helped.
Today I found in a german subreddit a guy, who literally has the same problem as me: https://www.reddit.com/r/gigabyte/comments/1t8oi5f/pc_freezing_for_a_few_seconds_again_and_again/?tl=de
I really dont know what to do and how to fix it. My BIOS has the latest update and im so confused.
