I have a dual-core Athlon PC that is refusing to turn on. I had assumed it was the power supply, so I've just purchased a new one. But after connecting it up I find that nothing has changed.
When I turn on the power, the only sign of life is an LED on the Ethernet socket that flashes on for half a second. Then nothing - no fan movement either on the PC or the power supply, no beeps, no clunking of hard drives, nothing.
My guess is a short circuit somewhere, but I am very inexpert on these things. I tried removing a few unused cards to eliminate problems with them, but no change. Any suggestions?
I have a multimeter if that helps...
UPDATE: It's alive!... I'm not quite sure what did it as I was plugging so many things in and out... thanks for all the tips.
