This article will not be long. It is just my answer to the questions of some of my friends who reported that their screen went blank (black) after logging on Windows 8.
When you log on Windows 8, the next screen that you will see should be the start screen. However, there are users who said that their screen went blank after inputting their password. I have been googling for a while to find the answer for those questions and many of the answers that I found said that the blank screen was due to graphic driver issue.
While hardware driver may be a potential cause, from my experience, there is another cause for that blank screen. And that cause is an antivirus program that I install earlier (I use Avast). If you encounter this problem, my suggestion is that you press Ctrl+Alt+Del so that you can access the task manager and kill the antivirus service that is currently running by using task manager. This solution may not work to everyone since not all antivirus program can be killed by using task manager. After killing the program, use task manager to run explorer.exe (File>Run New Task>explorer.exe)
Another solution that you can use is resetting your Windows 8 and reinstalling all programs that you consider important. To detect which program causes the problem, you may need to restart your computer whenever you finish installing a program. If your computer screen goes blank after installing a particular program, you should know that that program must be the culprit.
If you can affirm that Avast causes the problem, you have to prevent Avast's behavior shield from monitoring explorer.exe and systemsettings.exe. Refer to the following steps to do that.
