Laptop Dying! suggestions?

krazykuda, Ive already done that. I have been backing up my hard drive since the last hard drive crash. So at least my files are safe. last night no issues. So far tonight its operating ok but about every half hour it does not respond then the screen darkens for about 2-3 minutes then the hard drive message comes up. Then its good to go for a while. Thanks for all the suggestions. I hope to resolve this over the weekend.
