I purchased a new Dell Laptop Precision 3520, and it has been nothing but trouble since I opened the box. Now I am stuck paying for a computer that sits on the shelf. Every time I use it, it crashes and I lose my work. I was told that i need to uninstall the operating system. I am not an IT person. I don't have time for this, and I purchased a new computer. I should be able to plug it in and use it. Dell should have installed the operating system correctly. I have spent time uninstalling programs and reinstalling, with the same results. They are unwilling to work to resolve the problem, insisting that I "should be able to read simple instructions written in English", really? I will never purchase another Dell, and neither will any of my clients. And since I will be paying for this, I won't be able to purchase a laptop that works for at least a year, and it won't be a Dell. Crappy computer, poor customer service. I was told that Dell doesn't guarantee their computers. I didn't want a refund, I wanted them to either fix this one or replace it with one that actually works. Buyer beware, they have gotten too big to care about the little guy.
