I hope this is in the right section. A couple of weeks ago I left the house and came back and my computer had a blank screen. I tried rebooting but nothing. I figured my video went out and replaced it and nothing. So I figured I would try my recovery disk and when I use it is gives me a message saying there is no hard drive found. I replaced the hard drive and tried the recovery disk again and still the same message. What else could it be???
