I have turned everthing off at the mains switch..................except for the PC! and it still happens, last time it was late morning lasting through to late `ish` afternoon
(see textfile attachment)
It occurs at completely random times am, pm, sometimes not for days, but mostly for two to five hours at a time
I have also followed the advice given by Roseway
My very recent successful communication with my ISP in getting interleaving taken off the line has made no difference to this problem
