    I'm not expert on this but did you check hash of your WIN7 copy? If not, search the forum and get the appropriate copy and install it again.

    Cheers

    Dell Optiplex 755 has SLIC 2.0 ( For Windows Vista OEM SLP Key )

    Windows 7 requires SLIC 2.1. Therefore you can not use the OEM SLP key from above-mentioned list.

    You have to use a Loader or Bios Mod.
