I tried to restore my toshiba qosmio f60 back to factory settings as per instructions. Hold the zero while starting the laptop. It doesn't come up with the restore screen, instead it says (HDD recovery mode - windows is loading - starting windows) and then the screen goes black and the fan starts roaring and thats it. I left it for up to an hour and nothing happened. I recently put 8 gig ram in. Would this make a difference?
