I have seen this happen in two cases, different from thos already
described in this thread:

1: a Network coax cable with a faulty BNC connector that wouls
shortciquit when moved. Did the trick....

2: Power supply faults (brownout or spikes). I used to have 'em when I
switched on an old printer. Rewired the sockets (solif copper wire!)
and now it's ok.

Success!
