I hope I'm in the right place here. I have no idea what I have done to my laptop. I shouldn't have been playing and because of that I have made it worse.
So I accidentaly upgraded something maybe to service pack 2. After the installation my internet wouldn't work (I have telstra modem. I then uninstalled it thinking I could reinstall and the problem would be fixed but this didn't work.
In my search (on another laptop) I got a great idea to restore it back before I uninstalled the program.
Now my computer is even worse, lots of things seem to be missing eg the audio sound, when I plug in my memory stick nothing happens, when I look under the control pannel nothing is in there at all. I'm getting messages about an unauthorized change with windows error OxCOO4Eoo2.
I don't know what to do, I can't get on the internet to install any programs and I can't save them to my memory stick as its not being read.
Is there anything I can do.
Thanks for any help/suggestions in advance.
