You might try that and see if that helps.
Shut the computer down and then restart it.
Start tapping the F8 key before anything comes on the screen.
You should get a drop down with one of them saying "last known good configuration"
Arrow down to that and hit enter and follow the instructions.
In the drop down you also have "safe mode" if the first one doesn't help you can do a System restore to a date when everything was working right.
If neither of them helps, you may have to do a system recovery as the Tech suggested.
I'm using a eMachines ET1831-07 Desktop PC with Windows 7 Home Premium 64-bit. It has a Pentium Dual-Core processor, 4GB of RAM and a 750GB hard drive. The machine has worked great for the past few weeks, but when I turned it on today, Windows Aero refused to load. I tried the Windows Aero Troubleshooter, but it couldn't find anything wrong. Then, I tried to google an answer, but I couldn't get on the internet. I looked in the system tray, but there wasn't any icon for the network connection. I recently discovered that the Network List Service is disabled, and when I try to start it, it says:
v
Windows could not start the Network List Service serviceon Local Computer.
Error 1068: The dependency service or group failed to start.
The guy I talked to at tech support told me to back everything up and reload my operating system, but I don't want to have to go through that. Any ideas? Any help would be greatly appreciated! Thanks!
