In device manager: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
Windows 7
Toshiba Satellite L-40 laptop
How can I fix this? Is it because of a virus?
I have tried to "update driver" but it says my driver is up to date. I tried to uninstall and the scan for hardware changes but the same yellow triangle appears.
You could try rolling back the driver or restoring your system to a previous date. If it is a registry issue the restore will certainly fix this issue.
Run system restore and try to find a restore point that was taken before this issue, and use it.
If that doesn't fix the problem then the cd/dvd may be shot...
