Could also be a contacts if it is not the actual memory or board. A marginal contact where something is plugged in can over time build up deposits that make it fail. Of course, this is still a hardware problem, but can often be cured by reseating everything. If it is bad enough, it could also be exacerbated by reseating everything. ////jerry > > -- > | Jeremy Chadwick jdc at parodius.com | > | Parodius Networking http://www.parodius.com/ | > | UNIX Systems Administrator Mountain View, CA, USA | > | Making life hard for others since 1977.
