You did not say which form factor you have

Next go to Optiplex 755 manual ftp://ftp.dell.com/Manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/optiplex-755_setup%20guide_en-us.pdf
When open in Acrobat click on bookmarks on the left and select appropriate form factor, there look for System Board Components and Jumper Settings.

Anything else I can help you with?
If it is not working online, download manual to your PC, use Acrobat reader, which is free http://get.adobe.com/reader/otherversions/.
There is motherboard diagram, which is very difficult to show here and another page of instructions.
