The 1 and 3 diagnostic lights indicate a possible memory configuration or compatibility problem, according to the service manual http://support.dell.com/support/edocs/systems/op990/en/SM/MT/oM_MT_en.pdf page 75. It's possible a memory module is faulty or the configuration is wrong or the DIMMs may need to be reseated. I would recommend reseating all DIMMs and try again. If the issue persists it may be helpful to test DIMMs from another machine, or test the DIMMs one at a time in slot 1. Information on removing and reinstalling the DIMMs is also in the same hardware manual on page 25-26. Does that seem to change anything?
