Ways viruses can cause a black screen on computers

How do viruses cause a black sceen on computers?

A virus infection is one of the most annoying issues which can take place on any computer system. The infections can sometimes cause black screen errors on the system. You may get a black screen when you try to load the system. The issues occur as the virus corrupts some system components. With these corruptions, you will not be able to work with the system until these corruptions have been fixed. The viruses may corrupt the system registry and may encounter invalid values in the registry. The Master Boot Record (MBR)which is used to boot up the system may get damaged with infections. It is also possible that other system components like partition tables, NTLDR file and the Boot Sector are also corrupt with these infections.

Some tips to fix black screen errors on your system due to virus infections:

  • Using an installation disc

  • Troubleshoot the corrupt component

  • Clean the system registry


Using the installation disc


To resolve black screen issues on your system due to virus infections, you can use the installation disc of the operating system. You need to insert the disc into the system and turn on the system. As the system starts up, you get a 'Welcome to Setup Screen' displayed and you need to press the 'Enter' key at this time. You need to then press F8 key to agree to the license agreement. Then, you need to use the arrow keys to select 'Windows Installation' for which you wish to perform a repair operation. Press the 'R' key and then the 'Windows Setup' starts to repair the installation files. After a clean restart you will get the black screen issue resolved.

Troubleshoot the corrupt components


You can try troubleshooting the corrupt components which can cause black screen errors on the system. To get it fixed, you need to restart the system in Safe Mode at first. You can do this with pressing F8 key at system boot up. Then, you need to create a operating system boot disc to start the system. The next step is to run a good virus removal tool to scan the system for any possible infections. You can then repair the corrupt Master Boot Record (MBR) with the 'FIXMBR' command. You can use the 'FIXBOOT' command from the operating system recovery console if the primary boot partition is a FAT partition. This writes a new boot sector on the system partition.
Clean the system registry

The black screen might come occur on the system as a result of the virus corrupt registry entries. For this, you can use some online registry cleaner software.
