It was always going to be a shot in the dark, don't have any tiny itx boards lying around right now! lol. I try to stick to building standard sized pc's, this sort of problem doesn't happen then

I'll check for internal fuses, cheers. I'm pretty sure it's something power related, the external power supply seems fine as it's getting at least some power into the unit to power the dvd drive.

You should find the PSU is enclosed in its own 'shell'; which you might be able to open up. - There may be little glass fuses on the actual curcuit board. They need to be replaced with EXACTLY the same type - The rating will be engraved on the metal end-caps.

It could be the +12v line is up but something is interrupting another line...

Is it not a standard power supply connection to the board.

No, everything's different on the mini itx board and it's an external power supply.

It appears there is a small fuse on the motherboard that can cause this problem....now if only I could find it! I guess it might not look like a fuse in the traditional sense.

Obviously having not actually seen the board I can't be sure... Do a google image search for "surface mount fuse" ; they're odd little rectangular components - not like conventional cartridge fuses.

Well, it#s all in bits now! I can see a few possible miniature fuses, not sure how to test them but at least it's all come apart.

Biggest challenge is identifying it! - They're tested like any other fuse once out... Just a simple continuity test. Otherwise you'd need a schematic and a meter to trace the power lines.

Some actually are in little holders rather than soldered on...

Doh! duplicate post! - Sorry!
