There has been quite a lot of traffic of late concerning so-called "spontaneous reboots" and so far - *IIRC* - none of the incidents were directly attributed to causes _other than_ balky power spupplies, and in one recent case interestingly, a defective UPS!! I think it's probably worth shoving a new PS in there, these days they are far from expensive, in order to see if that eliminates further instances of the problem. I suppose much depends on whether or not you really want to -as you put it - 'dump the server'. Should you elect to do so, please feel free to ship it across the North Sea to me, I'll be happy to pay for the shipping, deal with its little idiosyncracies and give it a "second life" :-) Regards & HTH, -Colin -- Colin J.
