M17x keyboard not working properly

Hey everyone,

I just bought a new M17x about a month ago and it's never really even been used. Every time I try to use it, something isn't working properly. Internet Explorer doesn't work, It won't let me download Google Chrome, and Firefox has a blank about:home page anytime I use it. But the biggest problem is that the some of the keys on the keyboard only work sometimes. And then when some start working again, others stop working. I've had this problem ever since I bought the computer about two months ago and I've tried all troubleshooting steps and called Customer Support. CS simply stated that it sounds like a software issue which isn't covered by the 3 year extended warranty that I shelled out considerable dough for. So I paid about $4600 for this supposed bad-ass machine, which has thus far acted as the most expensive paper-weight I've ever heard of. I don't know what to do. Luckily I have my other computer to post this message, and hopefully someone out there knows something I can do to correct this problem. But I can say that I'm sorely disappointed in Dell's Customer Support. I don't believe that anyone should pay $4600 for a computer and 3 year extended warranty (that even covers spill damage) for a computer that doesn't work properly, then get told by customer support that they need to pay more money because it's a software issue when the damn thing didn't work right directly from the box. I didn't make any error other than ordering a computer that doesn't work right. Please someone help.
