Repair Windows 7 Black Screen of Death

Repair Windows 7 Black Screen of Death

Edited by Shaikh Saiif
BSOD, the infamous Windows error abbreviation, does not exclusively stand for "Blue Screen of Death". A slew of Windows 7 users have experienced having a "dead" PC with only a mouse cursor to interact with and a black screen to boot. In an allusion to the original BSOD, which was a label the Windows community gave to the blue error display that pops up after a system crash, the issue was named the "black screen of death."
There are different variations of the "black screen of death" depending on what caused the problem. Some BSOD instances could still allow the users to summon the Windows task manager and perform functions. However, more severe cases left the users with just a dead black screen and a movable mouse cursor.

What are the possible causes of Black Screen of Death?

The Black Screen of Death may be attributed to a variety of causes. Each of them is discussed in this section. Recalling the activities or events that had occurred prior to the emergence of BSOD could be essential in diagnosing the problem and in helping identify the ideal solution.

  1. 1
    Windows security update.
    One of the first major culprits for the black screen issue as discussed in the Windows community is a certain Windows 7 security update. Several Windows 7 users apparently stumbled upon the problem after installing, knowingly or unknowingly, the security updates code-named Update KB2607712, Update KB976098 and Update KB915597. While Microsoft has rebutted this claim, a slew of Windows users still claimed that uninstalling the said updates restored their Windows system back to normal. If you had installed Windows updates prior to the BSOD episode, there is a high probability that this could be the cause of the BSOD issue.

Malware.
  1. Several Trojan viruses such as those which belong to the "Daonol" family are believed to be capable of producing "black screen of death" symptoms.
