Sometimes when i turn my PC on there is no image, not even the mobo logo when turned on. But if i turn it on and off once or maybe more it boots up with an image and when it gets to the windows 8.1 pic it trys to diagnose the pc and repair but it fails and then gives me the option to refresh/reset + advanced options but none of the work, reset fails the disk verification and refresh just says something went wrong and i have no image or restore set up and start up repair just does a circle of when it turns on. Thanks for any help you can offer. The no image has thrown me of the dead hdd but i still suspect that.
