Query: a disappointing product

I bought this laptop on Christmas and it turned out to be an unpleasant Christmas gift for myself. The hard drive died all of a sudden after two months. Although Compaq replaced the hard drive for me eventually, I had to pay myself for rescuing my two weeks' work. The repaired laptop I got back from Compaq works poorly and I have encountered a lot of unexpected problems when running programs. In addition, the keyboard of the laptop is not reacing very well and the noise of the laptop is tremedous. These were problems even before the original hard drive died.
