Confirm no leaking or bulging capacitors on your mothboard.
refer to here
As this was a common problem with the GX280.
If found, you will need to replace the capacitors.
The other check is to make sure the heatsink is fitted correctly, perhaps reaply the thermal paste if you have any. I know that high temps would switch the GX280 off.
