Re: [H] Non booting case
Forget Duncan's insight, well intentioned but only vaguely accurate. That's not how you'd go about testing this issue since the power good line of the PSU is showing OK as the system powers up stays on depending on case orientation. When you say start I assume you mean power button jumper header on the mobo, I would not concern myself with metering the voltage across this jumper. Shorting it either powers on the system or it doesn't. Normally diagnosis of it the switch is manually shorting the mobo's powersw pins but you've replaced the switch anyway. Most likely something is loose that should be screwed down or the ATX power connector is not seated solidly into the mobo socket. Hence stand it on end, something shifts.

Re: [H] Non booting case
Sam, http://en.wikipedia.org/wiki/ATX IIRC, if you jumper pins 15 and 16, you will do the same thing the m/b's internal switching logic does to turn the system on. Please do not hold me to my choice of pins. Others in the collective have much more experience with this and may offer other choices of pins. And, in all truth, I have not really seen all that many true internal wiring problems in modern PC cases since ~1975. I have only seen one m/b whose internal switching logic went bad or died. I would focus on the m/b ground logic and/or the psu. Jumpering the 24-pin power connector should really be a last ditch kind of trial.

Re: [H] Non booting case
I am at a standstill on my checking. Would there be any danger in using a second known good psu and just plugging in the 24 pin main supply cable and leave the HD power on the old power supply? This would show up if there was a break in one of the power wires in the old power supply without just changing ir all out.

Re: [H] Non booting case
Sam, I once had an old 386 computer I sold to a friend. He called after setting it up that it wasn't working. I took it home, openned it up and checked everything. It was working fine. I closed up the case and returned it, and again, it did not work for him. Thinking it was something in his home setup, I made a housecall. Took the system apart to troubleshoot and it was working fine. Put it back together, and it stopped working. Finally, I saw the problem! Removing the case cover reduced stress somewhere in the motherboard that allowed the system to boot. As soon as I attached to case cover, the motherboard was strained and would not boot. I replaced the motherboard and all was well, again. Long story short, does turning the case on its side de-stress some part of the motherboard or some other connection. Just a thought and wag. Good luck. Jim Maki [EMAIL PROTECTED] -Original Message- From: Sam Franc I have an Antec case with a Gigabyte mobo that has a strange boot operation.
