Hi

I have been given a Optiplex GX270 that wont power up. Is there anyway
of confirming if the lack of power is caused by the Power Supply or
the Motherboard? The previous owner new very little about computers
and told me that this computer only needed formating. When I press the
power button I can hear the fan start up then shut down, maybe 2
seconds in total. The power button is orange for that time.

The GX270 had a 3hr car trip before I got it home, so the first thing
I checked was that the cables and cards were seated correctly. I took
the 4 memory cards out and reseated them. The 4 diagnositic lights on
the back show no sign of life, but there is a small orange light in
the middle of the motherboard that is on. I also had a quick look at
the capacitors on the motherboard, all appear ok.

Would I be safe in assuming that this is a dead power supply?

Cheers Mark
