Dell OptiPlex 790 does not start

I received a new Dell OptiPlex computer today, however when I switch on the power lights flash then go out and the computer does not boot up. If left for a while this can be repeated but still no action.

Symptoms seem exactly the same to what happened to me just 2 days ago - dead PSU. Now I am not saying this IS what's wrong with the PC but this happened me. Fortunately I have spare parts for pretty much anything lying around so I swapped the PSU and my PC fired up fine.

If just bought from Dell get on the phone to them and report it DOA. (Dead on Arrival)
