Solution For Windows 7 Black 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.

 possible causes of Black Screen of Death :-

 

 

1. Corrupted graphics card driver :-

Because the problem involves abnormalities in the system's display, it would be logical to consider an issue involving your computer's graphics card. The video adapter's drivers might have been corrupted or might need some updating.

2. 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.

7. Navigate to this particular registry location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
8. Click the WinLogon key. On the right pane of the window, find the "Shell" option and click it. The value of the Data column should be explorer.exe. If it isn't, change the value by double-clicking Shell and typing "explorer.exe" in the Value data input field. Once the change is made, click OK.

If you can't access the Task Manager, you can boot your Windows PC into Safe Mode and  uninstall Windows security updates from there. To do so, follow the steps below:  

1. Press the "F8" button on your keyboard upon booting up your PC. This will bypass the normal boot process and leads you to the advanced boot options instead. Note: There is a small window of opportunity for this process to work so you may want to press the button repeatedly to ensure that you won't miss that opportunity.
2. Click the "Safe Mode" option once you are in the Advanced Boot Options screen. The system will now load the files necessary to boot into Safe Mode. Wait until the login screen appears.
3. Log on to your computer. If you have many user accounts on that computer, make sure that the account you logged on with has administrator rights.
4. Click the Start button and search for Programs and Features by typing "programs and features" in the Windows search box. Click the first search result.
5. Locate the "View Installed Updates" option on the upper-left portion of the ensuing window and click it. A list of installed updates will be displayed
6. Locate the updates under the "Windows" category.
7. Observe the name of the updates and the dates they were installed. If there are updates with the code name KB2607712, KB976098 and KB915597 and they were installed immediately prior to the occurrence of the "black screen of death", uninstall them by right-clicking on the update name and clicking "uninstall".
8. Restart your computer into the normal Windows mode (not Safe Mode). And don't forget to cross your fingers.

4. Scan and remove Malware :-

If you can't access the Task Manager in the normal Windows mode and if the previous step didn't solve the problem, you should consider scanning your PC for malware through the "Safe Mode with Networking" advanced boot option. The steps to doing this are detailed below.

2. Click the "Safe Mode with Networking" option once you are in the Advanced Boot Options screen. This will allow you to have internet connectivity while on Windows Safe Mode.
