So I upgraded my system fine, then sold the old mobo & processor, ram & case to a pal.

When I build his new system, which involved (for reasons I won't go into) moving the board out of the case then back in again, suddenly the system won't boot. It is only the light on the speakers (which take their power from the keyboard socket) that confirms that there is power. There's no post, no fans etc. It just sits there.

I took all the usual anti-stat precautions, I have triple-checked the fiddly little connectors (power sw for example!). I had no need to change any jumpers from its last known working state. I have reseated the ram, changed it's sockets, stripped the whole thing back to basics (no cards, no drives)

In desperation, I shorted the cmos jumper, then forgot to replace it before trying to power-up (not reccomended). To my astonishment, I got a post, single beep, then it naturally went beserk looking for drives & things it couldn't find, then kindof screamed ( a continuous tick, a little like a full keyboard buffer) before freezing.

Powererd off, reset the jumper (back to "keep settings"), powered on and once again it sits there as dead as the proverbial... I don't think it's fried, cos I can repeat this trick with the jumper and get a result. During the boot, it checks the ram & reports ok, it identifies the processor ok...

It must be something obvious that's wrong, but I'm stumped. Can anyone suggest anything to try? (Is anyone here?)
