I wanted to fix my screen saver in w10. Instructions said I have to delete img105. Before I can do that I must own it. I tried but, it kept denying me saying I needed to activate my hidden admin account. I did that per the instructions and Wham! screen is black ! I tried a hard boot and all it does is sit there with a black screen and a surging fan! I tried to see if it would boot from a cd of windows 7 pro and no luck. Doesn't read the cd. Did I fry my hard drive or something? Mayday !
