Old Mobo in new case won't even post to BIOS

[Cold_Gambler]

My father-in-law's P4 (I'm not exactly sure what it is) died on him (unclear on circumstances of demise) and I asked if he had thrown it out as he'd already bought a new machine. He hadn't and as it is a rather nice Antec ATX case, I asked if I might have it to replace my crapola cheap box I've had since 2001 that has seen me through two motherboards and countless other upgrades.

I took out almost all the components in the Antec case with the exception of the PSU,

My money is on the PSU being buggered M8.

Alternatively are you 100% that there were no extra stand-off posts in the case that were touching the mobo circuit?

Count the posts and count the mounting holes in your mobo, and make sure when board is in place you can see all posts through the mounting holes.

Hmmmm... thanks Roger.

I figured the PSU was probably OK given that there's some power... I'll have to ask my f-i-law what the symptoms of death were.

Anyone know how to confirm if a PSU is not providing power to all the rails?

Amp meter would be my guess.

Cold_Gambler,

Heres some documentions out of an older book I have. Hopefully its still up to date enough to be usefull to you.

You'll need a volt meter, a cheap one will do.

Here are the ATX allowances for power supply voltage spec

And here some guy explain how to test PSU not plugged into a power supply.

Ooops I meant: And here some guy explain how to test PSU not plugged into a "Mother board"
