Kroeneker - take it you're saying the light on the front won't come on when you press the 'on' switch? If so I have exact same problem. Very much doubt it caused by overheating. But I have, what I consider, a very interesting theory of what is happening. If it's true we are both in the clear. Just posted the below, in the thread mentioned above. Any thoughts?
But have a theory about this:
A few posts further up, yesterday, someone was asking the same question - seemed like: bit ambiguouse. They made the point I should have made: that had kept swithching computer on and off a lot before problem developed (trying to get a network up with only one keyboard.)
: BIOS is *designed* to stop the ignorant from buggering the computer; if user keeps switching on and off with low time, measure by clock, between it does what has happened to me, it refuses to switch on untill some time has elapsed. The appauled punter rings the shop; the shop says 'calm yourself my dear' or 'That'll be a few US cents' if there's no warranty. Think this entirely possible.
(Possible the people on here might not know this as common knowledge for they do not ABUSE the on/off button and they have a shed load of keyboards and everything else you can think of.)
