Ever since about a day or 2 ago when I tried to torrent Sony Vegas, this happens. First I tried to delete the Sony Vegas because it wouldn't work, because my anti virus deleted the program that let it run, the when I went to delete the program my screen when black and then I tried to restart, and it only gave me a black screen with the cursor, I could CTRL+ALT+DELETE, but couldn't get task manager to load. I then had to have a system reset, from before I uninstalled Vegas, then my computer was fine, but then I tried to install Razer Synapse, and it took forever for a simple download, so I tried to close out, and it gave me the black home screen, and task bar, then I would restart and the same as before all black screen with cursor, and I could CTRL+ALT+DELETE, had to do another system reset, but tried to do it from before I even installed Vegas, and it wouldn't let me? I have no idea what to do, it isn't affecting my computer, other that really annoying me, and not allowing me to install programs. Virus maybe?
