I've been having this problem for almost a month now. My desktop keeps on shutting down by itself everytime I play valorant or when I'm just browsing and also keeps on popping up calculator. At first I thought it was the power supply so I bought and changed it and for a week it didn't shut down by itself anymore so I thought its fixed, then when I downloaded Valorant it started shutting down again so I don't know what to do anymore. Already tried all anti-virus and malware and everything was clean. I don't think its the graphics card since it doesn't shut down when I play Dota 2. It only happends with valorant and sometimes when I'm just browsing the internet. Can anyone give me advice on what seems to be the problem because I'm really starting to get depressed with this.
