Open up the case and remove any add in cards and memory modules. Try to start up by adding these back one at a time until the unit stops booting normally. The light combination is not one recognised in the user manual so I am guessing you have a non-descript fault with one of your components. Be careful when you open the case as to not disturb the ribbon to the motherboard which controls the power, I have had a very long experience trying to get one of these reconnected!

Hello everyone, check your cpu - I've just had one of these in for repair and the cpu was faulty - removing the ATX 4way 12v lead let the pc start rather then detecting a short and shutting the psu down. Changing the cpu cured the fault.

you can go to dells website and click support drivers and downloads type in the service tag of the machine (its 7 letters and nubers found on CPU Ex: BF14FJ1) and based on the service tag the correct audio drivers should be displayed for you to download.
