Re: DELL XPS 730x with SP2208WFP Monitor, BIOS Problem?!
I am sorry to tell you this but it is a known problem with the 730x and Dell will not be fixing it. I have the same issue with mine if I have a USB hard drive or any other USB device other than the keyboard and mouse connected. What I did was take all of my USB drives and put them on the network to get around this issue.
I have called Dell on this a number of times and they said there was nothing that could be done after verifying all of the Bios settings. Other than this issue it is a great computer and because I put all of the hard drives on the network now everyone in the house can share the files.
I had this with both Vista that was on the computer when I received it and with Windows 7 that is on it now.
