Power Supply Problem.. PLEEZ help L@@K

[Dctm]

Following specs:
abit kt raid
amd thunderbird 1.0 ghz
300 watt antec

I built a rig earlier this month and it worked properly. However noticed that when I turn the power on, it flickered and didn't work. Fidgeted with a couple of lines and it worked. That was a couple of weeks a ago. Now it doesn't work at all. Turn on the power and the light flickers and doesn't work. Tried fidgeting with the wires, doesn't work. Took everything out (hard drive, ram, video card, etc) and set up for mobo, cpu, and fan is all that is connected. And this doesn't work. Anyone have any suggestions?? thanks

Try another PSU,I had a 9 month old AMD approved go faulty that would try to start but the lights just flickered then died again.

Try a different power supply cord. I've had similar problems with 2 different cases.

cord as in plug?? if that's the case.. tried that.. and it wasn't the problem.. don't know.. it's an antec 300 watt and it shouldn't have shorted out.. have no idea whats wrong.. but will buy another PSU

Are you getting any standby power (+5v on pin 9, purple wire next to yellow wire at the end of the row)? Some motherboards have an LED to indicate this, but it's better if you unplug the ATX connector from the motherboard and measure it directly (between purple and black wires), in case the motherboard is shorting something. If that works, get four 10-ohm, 10-watt resistors, connect them between the red and black wires, and momentarily blip the green wire (pin 14, between two black wires on the same row) to turn on the supply. You should measure +5V on the red wires, +12V on the yellows, and +3.3V on the orange wires. If not, try blipping the green wire a few more times.

Most likely the supply has a blown fuse (may look like a resistor) or two shorted power transistors. The transistors are usually just $2-5 apiece.
