First: Whenever i boot up i get an "Error: there's already a username on this network" or somthing liek that. Also, a bunch of installer things come up. I think this happened because i deleted some files I probably shouldn't have.
Second: My background is nothing but blue. I change it, and whenever i restart it shows up for like 5 seconds but is soon covered up by the blue.
Third: My internet has been spiking and running slow lately. It doesn't always run slow , but every once n a while (and it's a pain when im in the middle of an online game) it gets really slow
It all started a little bit after I cleared my computer of malware, and then I think i started deleting important files.. then i tried a system recovery and that made thigns even worse. So i figured before i ruin my computer, i'd like some help. Please and thanks!
also, if it's possible i'd just like to clear everything off my computer and start brand fresh, i don't know if there's a way to do that. (but i'd save my pictures, music, and some other things)
