I have a Dell Optiplex 780 SFF which fails to boot up. Every time I plug in the AC cable, the power light turns amber and that could wo diagnostic lights, 3 & 4 light up. I have tried many different things like removing and moving the RAM. No idea what could be wrong. Don't know if it could be relevant but we had a power cut the night before it cut out.

Hope you can help,

3 and 4 does signfy a RAM problem click here the power cable - press and hold power button for 30 secs - refit power cable and attempt to boot.

if still same try one stick of ram at a time - try in different slots. I The power outage may have damaged the RAmM or worse may have damaged the motherboard.
