i've been having computer troubles for the last week. steam won't load. youtube videos replay themselves sometimes, or just end randomly in the middle, as if they were uploaded for a shorter time period than what they were supposed to, or they start getting video errors, such as pixelation or green screen errors. some images won't load, they'll stop half-way down before turning to static then a grey spot. like a corrupted jpg file. it also screwed up blockland, therefore i have to constantly re-enter my key, but i don't have it anymore so i can't, so i haven't played in 3 months. my anti-virus (malwarebytes) says it hasn't been updated since 22 days ago, but it said that as soon as i downloaded it to try and fix the issue. i ran a scan it came up with nothing. my mother downloaded all these other useless anti-virus programs like windows defender or whatever and it came up with nothing. we tried to reformat but we can't. (or my mother doesn't remember how to) we can only restore back to april 26th, but that's work either.
can i get some help please, like how to reformat so i can try it myself, or something to fix this stuff without reformatting.
i'm going to run another scan, then go to bed.
