My almost 1 year-old Gateway laptop is having problems with starting up and shutting down, specifically blue screens and also black and white stripes screens. I have no idea why my laptop is behaving that way at start-up and shut-down, but I can rule out that it is not a problem related to viruses. When I first had my laptop for the first few months, none of these problems occurred until after half a year did I encounter them. I started to have these problems probably 2 months ago, but they hardly occurred. The very first time when my laptop had this problem was that it had a problem with freezing at shut-down. I would be able to go to the start menu and press the "Shut Down" button, but whenever it gets to the screen where it says "Shutting down..." it freezes and never shuts down. I also noticed that the laptop was very hot. I've had this problem probably about 3-5 times already. I've tried cleaning my laptop with CCleaner, but it doesn't change anything. If it helps, my laptop has a 500 GB Hamachi hard drive. Well, some time ago, I briefly read something about Hamachi hard drives are renowned for hard drive problems/failures. Does the hard drive have anything to do with the causes of the blue screens, as well as the black and white stripes screens? Any help would be greatly appreciated because these problems are occurring almost every week now.
