I have 2 Dell Optiplex GX 280, both having the identical problems. In that they don't boot, powers on but doesn't have any display. The cpu fan starts spinning low then gradually increases it velocity I have to turn off , afraid of damaging fan.What can be causing this as memory tested good in other systems.

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.

The first thing to check is the power supply. Test it or try replacing it.

I agree with Lordy123. It sounds like Capacitor Plague:

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.
