My Toshiba laptop has been bluescreening more than usual and the fans and RAM have been really taxed lately and I do not know why. When I am only using Google Chrome, my 4gb RAM is at 50% capacity and my fans are running at almost full speed. My computer has also been crashing (bluescreening) a lot more than it used to, crashing around once a week as opposed to never crashing like before. I have run Malewarebytes and it came up with nothing. What should I do?
