When i load my laptop the screen is black, so i go to the task manager and run "explorer.exe" and it works, but every time i load my laptop, i have to keep doing it. is there a way to set it to happen everytime?
Does it work in Safe Mode properly? Did anything happen before this started? You should do a virus and spyware check if you have not yet, you can create a boot disk for that, Avira Antivir has one you can download and burn.
Likely you will need to end up doing a re-install of Windows if a virus scan does not fix things.
