I built my own PC for the first time during the summer of 2018. It was a budget build, but it works for me. Around last year, my PC started to freeze once a week. Specifically, the screen would freeze on whatever I was doing. The PC never formally crashed or anything. It just wouldn't respond to any mouse movements or keyboard commands. The webcam, keyboard, and power button all still lit up. The only thing that worked was rebooting. I'm a lazy person, so I kept doing that instead actually fixing the issue. Over time, it increased to once a day. Always from 4-8, if that's important. But this week, the frequency increased again to once every couple of hours. I have no idea how to begin to troubleshoot this problem. Any help would be highly appreciated.
