Have you googled your laptops make and model to see if you are alone in ths problem? I had a laptop from 1999 that did that behavior and it was the hard drive. Once day I went to boot up and instead of seeing windows 98se I saw the scan disk blue screen and it froze at 51%. That was it.
I got a surface 2 and it rocks. You just cant install any software on it.
Otherwise go with the Pro series.
