Dell Inc., USA Consumer fraud Internet

I bought a Dell XPS M1530 laptop in march 2009 with a 3 year warranty, customized.In 5 month the harddrive broke along with the speakers (my computer froze and I lost ALL the data), after replacement made 5-6 months later it froze again and the motherboard was exchanged along with a new charger. 2-3 weeks later it froze again and the mother board is probably broken again and half of the keyboard is not working either. I paid $995 for this computer which should work at least a full year with no problems. I believe Dell sold me a faulty computer and now keeps replacing parts with refurbished parts and when I started to complain really hard, they offered to replace my computer for another refurbished one which I thought is completely unacceptable and unprofessional. I want my full refund because the product is faulty and service awfull. I called all departments and they said, refund is not an option and adviced me to go to technical support and get it fixed, which I tried and it did not work. I feel I`m in a magic circle and I think this is fraud, to sell someone something bad and later not taking responsibility for it. Shame. And I`m very very dissapointed and helpless what to do next. I really want my money back!
