At first whenever I tried playing a game such as "Mount&blade" or any non-steam(online gaming platform) online game my computer would restart and end up to a screen that states "no boot device available". Now whenever I log in to my first account it'd automatically restart and redirect me to the "no boot device available" screen. I've stayed logged in to my 2nd account and so far and it hasn't restarted or done anything at all. I don't know this might be related to using disk check to clean up my computer or if I may need a need hard drive. I'm not really good with computers so I apologize in advance if my explanation comes off as incoherent.
