From power off state, I have to unplug the psu to re-set the PC as after the pw button is pressed the boot fails. I note a MoBo led indicates power but this has repeatedly faded at the same time as the power cuts everything, but the USB bus (which still has a voltage the lights are on). I then have to unplug the psu, wait about 5 seconds, then re-plug in. Sometimes it goes straight to boot without an 'on' button press, other times it needs the press, then jumps between the two. I'm trying to keep the thing going full time to prevent 2-3 hours repeating the above :-( once it's booted and the drives are all running it seem ok, but ive tried running with all the drives I could have disconnected, disconnected, even floppy, (and with USB disconected at the MoBo)

I'm not sure which way to jump PSU MoBo or CPU ??

I'd start with the PSU personally, as that is probably the cheapest and easiest one of the three to replace, especially if you are like me and have several extras just sitting around the house =).

I suppost so, 'fraid I almost resigned to replace psu, even though it is only a few months old. Unfortunatly no psu's about that work, or aren't in another unsuitable PC (a dell :-( ).

the psu in a dell computer is the same as a psu in pretty much any computer (maybe a little weaker though), but it would probably still work for testing purposes, unless it's one of the huge crazy psu's like the ones in the precision 530's.

yikes, that's a bit suprising, what system is it?
My dimension 8300 has a weak (but not THAT weak) 305 watt

I would say PSU also, and you have to be careful about replacing Dell power supplies.  You may need one of these if you use a standard ATX power supply (and 200w is too small these days): http://www.endpcnoise.com/cgi-bin/e/dellconverter.html

To my knowledge it is also possibly that your soft power is malfunctioning. Try to unplug your soft power and to turn on your computer you will need to jumper the two posts that the power switch connects to it might not be the power supply sio I would try that first since it wont cost you anything to try
