Greetings- I just moved my prop operation from going to office to trading from home. I bought a new Dell Dimension E510 on Ebay and 3 19" flat panel monitors. My problem is this: the hard drive makes a VERY loud rattling noise and it has gotten worse since I set it up. I am still waiting for the warranty transfer to occur from the EBAY purchaser to me, however, I suspect I might not be covered by the time this occurs, if it hasn't expired already. I don't want to use the computer as I don't want to make the problem worse and clearly I am not techno savvy. Has anyone experienced this sort of problem or have a diagnosis/solution? I would like to get back to trading ASAP and cannot go back to my office. Any constructive advice would be appreciated. Thanks in advance.
