I am feeling sorry for computer man. I am also feeling sorry for myself. Picked new computer up again but was busy so did not connect it until today. R may have wanted to look at a pornographic site last night, so the last thing I would want to inflict on him is a defective computer.
I connected it up today and while all the previous mentioned things have been replaced, I managed to make it fail on the first site, The Age, the second site, Yahoo mail. All done within a minute and yet computer man took it home and surfed on it, surfed on it in in the shop, left it on all the time, and it will not fail for him.
I got busy with extension leads, various power sockets and circuits and have absolutely established it is not a power supply problem.
I have tried cordless and corded keyboard and mouse. Printer works fine.
Only one thing left. The Telstra modem.
When we moved here, the Telstra tech person came the first day to connect us to the back bone wired cable internet in the building. He could not make it work with the six year old cable modem. He tried a new modem after some hours of playing, and suddenly it worked. After complaining to Telstra about having to buy a new modem, they paid half.
I think we are about to go down the same path. I will suggest this to computer man and maybe he can lend me a newish modem to establish that internet connection is the problem.
If you want a ripper read of how bad Telstra can be, take a read of Victor's post on trying to update his Foxtel connection.
