Hi Samantha
Jobeard is great with Network issues: I have turned to him for guidance more than once!
So, you are in good hands!
I would like to offer some observations he did not mention, and offer some diagnostic questions.
plug all my computers out the wall sockets at night because we have lightning storms.
It seems even though we did this, our network connections are scrambled
and one of our stand alone computers doesn't work.
The power button is on, but no one is home.
How can this be if the plugs were all pluged out.
Also, what can be done to re-establish the connection?
It seems to me, you may be saying that one of the computers will not even boot?
If the rest of your network is up and running, it looks like this computer may have failed.
First disconnect this machine (nobody home) from the rest of the network, by unplugging the network cable at the back of the computer.
Next...
- Is the monitor turned on?
Was it unplugged from the power source during the storm?
Is the monitor connector securely attached at the computer? What about at the monitor?
- Are there any lights on the computer (power or drive activity lights) when you try to power on?
Are there any beeps at power-on?
Some systems have some lights on the back of the machine that offer trouble shooting codes. Does yours?
- Have you double-checked to make sure there is power at the wall? (where you plug this computer in; it may be a bad outlet)
Have you double-checked to make sure the power cord has not come loose at the computer end? (also at the monitor)
- Have you tried all of this with the computer disconnected from all peripherals? (scanners/printers, router, etc)
- As the system tries to start, do you see anything on your monitor at all?
If you get it to boot while disconnected from the network, then turn it off, and reconnect your network cable and try again.
Please let us know your results.
If all of this is too basic, please forgive the interruption.
As I read your question, it simply occurred to me that you may have something more basic at issue than your network connections.
