it used to work fine then about a week ago it started to freeze. i thought it had a virus so i tried to run a scan and it just froze again. i went on it again today and it is still freezing, i ran windows malicious software removal tool and it didnt find anything. When it freezes i have to restart it incorrectly then it comes up with a thing and asks if i want to start StartUp Repair. I do this, its fine, then freezes again and the cycle returns. Please help. I’m really worried.
