I turned on my Toshiba laptop today and I got the blue screen of death and it turned off by itself and when I tried to reboot it nothing happens not even the Toshiba sign comes up like it usually does and I don’t even see the blue screen of death either. I'm guessing it’s the laptop hard drive that’s the problem. If I replace the hard drive you think that will fix the problem because I don’t want to buy a new hard drive and spend the time replacing it to find out that wasn’t the problem. Any feedback would be greatly appreciated. Thank You
