That series(gx240-gx280) was notorious for bad capacitors on the motherboards and bad power supplies. I would suspect those first, there will be a line of LED lights on the back near the I/O ports, what are they displaying? Is the power LED green or orange? Is the PC emitting a beep code?
Let me know and we can narrow it down.

I agree with Lordy123. It sounds like Capacitor Plague:

Tried other PSU & capacitors look good , no swelling of indication thereof or even sign of a burnt cap

I have seen this in a couple of GX280s and, judging from postings here over the past year or so, this model was apparently notorious for this specific problem. Troubleshooting with a POST 4 card produced both no, and inconsistent, results. I was never able to find a satisfactory solution, and ended up recommending that the customer replace them with a more reliable platform.

also note that bad caps are not blown up, or leaking in all cases..
