Hi all,

I guess I should start by listing system specs:

Intel i5-3470
2x4GB DDR3
Intel DQ67SW
GTX 780

Things I've tried so far:


  • Boot with only one DIMM/no RAM at all.
    Remove the 780 and boot using integrated graphics.
    Remove all storage and peripherals.
    Remove CPU (!) and power on.
    Tried a different PSU (500w also) - I know both of these PSUs to be functional.
    Remove motherboard from the case (in case of grounding)
    Using various displays and cables

Each of these scenarios yielded the same outcome: fans spin, LEDs light up, USB doesn't seem to get power (LEDs on peripherals don't light up).

I'm certain that the inbuilt speaker works - the motherboard beeps when the BIOS configuration jumper is removed.

Connected monitors detect that they are connected to something but go into standby as if the computer were off.

Considering the above, I suspect a faulty motherboard. Is this likely to be the case?

Any and all responses would be greatly appreciated.
Kris

Thanks for the reply.

That was my thinking too. I'll phone around local PC shops tomorrow to see if any of them have a suitable motherboard I could use to test with.

Wish me luck!
