Formatted My Notebook

I formatted my notebook and things still don't seem to be working well. The blue screen errors and dumping of memory thingy still exist. It is nothing to do with the hard disk and I don't think it's the software or window XP corruption. I have been formatting it for so many times till I finally decided to let it remain ON forever until I got my replacement notebook. I will put it to sleeping mode when I'm done with my stuff. So sad and couldn't believe that I can't fix it even after sending it to the expert and original dealer, HP. :-(
