Help diagnose DOA system?

[Goof]

Took delivery of a used system yesterday - AFAIK working, but so far it's DOA. It's got an Asus P6T deluxe V2 mobo on it. The power switch action felt a bit funny, so I was investigating that and noticed the connectors from the pwr/reset on the board were the wrong way around

So I sorted that, but still no boot, completely nothing, not even BIOS beeps. I tried clearing the CMOS but still nothing. The mobo has an inbuilt power & reset switch so I tried disconnecting all the front panel cables and using the onboard switches - still nothing. Also tried removing 2 extra dimms.

The only sign of life is the fact that the onboard power and reset switches (on the mobo) are flashing (simultaneously). I can't seem to find the guide in the manual as to what, if anything, that indicates though.

Can anyone help?

Manuals can be found in the Manual and Documentation tab. Have a look to see what the flashing lights are?

Thanks Nicky - I'd already downloaded that and had a pretty good look through it, what I meant was I can't find a 'legend' to explain what the flashing means. There's a page specifically on the internal buttons but just says e.g. these turn on/reset the system
