I have two motherboards. An ASUS P3C-2000 motherboard. That is an i820 chipset motherboard with a Slot 1 connector. I use a slotket to use a FCPGA 550Mhz PIII along with an AGP 7000 vid card and 256MB of PC100 SDRAM.

The second setup is a SOYO P4i865PE Dragon 2 Plus version 1. It's been tried with a 2.8Ghz 800Mhz FSB processor with HT and a 2.0Ghz Celeron 400Mhz processor. Also 512MB of DDR 3200 ram. (sometimes 256MB of either 2700 or 2100 ram with the Celly). Sam Radeon 7000.

On both systems, I hooked them up to a little face panel I keep witht he switches on them (PWR, Reset, HD LED, etc.). Neither of them boot. Both have a green status LED and the Soyo has a red LED in addition to Green to indicate if there is a problem with the GPU connected (AGP of wrong voltage signaling etc.)

On the ASUS, I plug the power cord to the PSU, and everything remains ice cold except two components. The southbridge is mildly warm (the northbridge is still ice cold), and the ITE PCI to ISA bridge connector blistered my finger before I could take it off the chip. Something tells me it isn't supposed to get that hot with just the power cord connected to the PSU. The status LED is still green. I hit the Power switch and nothing happens. It just sits there.

On the Soyo has the same green light on. Nothing gets warm. I hit the power switch and nothing happens. Just sits there with the same Green status light on.

I have used 3 different face plates and 2 different power supplies. One is 250W (real watts) and the other one is a 350W (probably not real, as its far lighter than the 250).

Both of these PSUs powered either rig at one time or another. Its only a single HD, optical drive, floppy drive, and then the mobo with ram etc.

So have two mobos shorted themselves on me? They stopped working at different times. It's just that no matter what I do I can't get these things going again. Anyone have clues?

well, can you test those psu's on a system that is known to work and that can handle such low wattage?

No, right now unfortunately I don't have the components to build another machine. If I had a new mobo I wouldn't even care..

I had the 250W PSU was from an Emachines. The 350 came as a P4 bundle. I don't have a multimiter. I'm afraid to screw up the Seasonic 430 running my AM2 rig.. It's my current server and I really would rather not risk its components.

The 250 doesn't.. I reckon the 350 is to damaged to.. (I got the 430 after trying to run the P4 and 4HD's plus 2 optical drives.. messed up the board to where it couldn't overclock but it still ran).
