Please someone give me an advice or tell me what you know.

Guys is it ok that I've installed windows 10 times in 2.5 Years on my gaming laptop? I've reinstalled Windows back then when windows 11 wasn't able to handle gaming and switched back to 10 and then reinstalled 11 after few months as i heard win 11 is well optimized for gaming. Then i reinstalled few times because of some virus attack that i have no clue how. Then i reinstalled it 1 time cuz the free space amount was wrong and tried everything to solve that bug or whatever it is so i had no choice and reinstalled it. Now my games are crashing after playing for 3 hours even my temperature never went over 70°c. This might be my fault because i watched some dumb video on Youtube to optimize my Laptop for gamimg and Done some shits. I'll never do this again & Im gonna reinstall it now for the last time
