Microsoft say that patches it released on November 10th are not to blame for the recent spate of report black screens after users log in to their Windows NT, 2000, XP, Vista and 7 systems. The phenomenon has been dubbed the Black Screen of Death, a half hearted poke at the infamous Blue Screen of Death that typically follows a cataclysmic turn of events for a Windows based system.
According to the BBC security firms have suggested that the latest round of patches issued by Microsoft are to blame for the mysterious turn of events. Microsoft however are currently investigating the problem and stated that their "November Security Updates are not making changes to the system that these reports say are responsible for these issues". Microsoft instead says that Malware such as Daonol is to blame and says, users experiencing the issue should contact Microsoft Customer Services.
When a user logs into an affected system, they see, well nothing really, just a black screen. No taskbar, no icons, wallpaper or any menu system whatsoever, just black. A lucky few have been presented with a My Computer window, but generally the system grinds to a halt. Not knowing what else to do, some users have resorted to formatting their systems. But if you haven't already taken the plunge and resorted to the extremes of a format then there is a possible solution for you.
Prevex, an IT security firm has issued a set of procedures (see bottom of article) that you might want to try, that could solve your issues. There is no guarantee that it will work, but it's worth a try before you go formatting.
The crux of it is this, if you know how to pull up Task Manager (Ctrl+Alt+Delete at the same time) and run a program from it just enter the following including the double quotes into the Create New Task box: "C:\Program Files\Internet Explorer\iexplore.exe" "http://info.prevx.com/download.asp?GRAB=BLACKSCREENFIX" . When prompted click run, and not save. After the program has downloaded it will do what it has to do and you will have to reboot your machine.
When you log back in, you should with any luck have a fixed computer, but as previously stated this may not work for you. Prevex say though that if the black screen of death has only just started to occur after applying the latest MS patches or if you have run anti-malware programs, then there is a high likely hood that the fix will work.
