NEC warrenty service and support

Hi all,
    After 10 repair jobs, all in warrenty, NEC refuses to help us with our NEC.
It is desktop tower "Ready 9704" 200Mhz with a 3.2 Gig drive. This machine is 8
months old. Every three weeks the keyboard and mouse drives get lost and NEC
tells us to reinstall Windows 95. The same problem happens a few weeks later.
Thinking it was a hardware problem, NEC replaced the Hard Drive, Mother Board
twice, Power Supply, and Floppy drive. Nothing has worked.
    Nor will they refund our money or replace it with a new computer all
together. Basically, we are stuck with a broken computer and no refund.

    Also, has any one had problems like this?? Is there anything we can do to
help allivate this problem or should we get a good theorpist. If anyone has
ideas, please let me know.

Thanks for listening
Brian
