    I was given a Dell Optiplex 755 with a bad hardrive.

    I swapped it for a 1.5tb Seagate and installed Windows 7 Ultimate a friend gave me. He Dl'd it from somewhere and hasnt had issues. I've been using it since September without issues accept for not being able to activate it.

    I've re-armed it twice to give me 30 more days.

    I've tried Keys found here http://forums.mydigitallife.net/threads/10370-Windows-7-OEM-SLP-Key-Collection and checked them with PID checker

    Every time I go to activate I get "Error code 0xC004E003"

    Any ideas?

    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.
