Bonjour,
 
Je dispose de Windows 7 Edition Famililale Premium et un PC récemment acheté.
Je suis "victime" du fameux symptome de l'ecran noir après la saisie du mot de passe (parfois j'obtiens la main au bout de qq minutes ...).
J'ai pu lire dans la presse que des patchs de Microsoft avaient été mis en cause (notamment 2 qui sont installés sur mamachine) par la société privx.
Il y a eu des démantis depuis ...
Bref, moi j'ai ces fameux symptomes et je ne sais pas comment diagnostiquer le pb ...
Est ce que qq'un a une idée? un retour d"expérience? Auprès de qui je peux me renseigné?
 
Pour infos ma config est consitué d'une CM Gigabyte GA-P55A-UD3, Intel 860, SSD Intel, ATI 5770 ...
 
Merci d'avance pour votre aide!

Prevx offers a free fix for Windows Black Screen
Firstly, there appears to be many causes of the black screen issue. The symptoms are very distinctive and troublesome. After starting your Windows 7, Vista, XP, NT, W2K, W2K3 or W2K8 PC or server the system appears normal. However, after logging on there is no desktop, task bar, system tray or side bar. Instead you are left with a totally black screen and a single My Computer Explorer window. Even this window might be minimized making it hard to see.  
 
 
If you have these symptoms you can safely try our free Black Screen Fix. It will fix the most common cause we have seen of this issue. Running the fix program is easy under normal circumstances, simply download with your browser using the link above and run the program. However, if you are trying to do this from the PC which has the black screen it is a bit more tricky. In these circumstances follow the procedure below:  
 
 
1) Restart your PC  
 
2) Logon and wait for the black screen to appear  
 
3) Make sure your PC should be able to connect to the internet (black screen does not appear to affect this)  
 
4) Press the CTRL, ALT and DEL keys simultaneously  
 
5) When prompted, Click Start Task Manager  
 
6) In Task Manager Click on the Application Tab  
 
7) Next Click New Task  
 
8) Now enter the command:  
 
 
"C:\Program Files\Internet Explorer\iexplore.exe" "http://info.prevx.com/download.asp?GRAB=BLACKSCREENFIX"  
 
 
Note this command assumes that you are using internet explorer as your browser, if not substitute your browser path and file details for those of iexplore.exe or use the Browser option of Task manager to locate it.  
 
 
9) Click OK and your browser should start up and begin the download process  
 
10) When prompted for the download Click run, the black screen fix program will download and run to automatically fix the issue.  
 
11) Now restart your PC and the black screen problem will hopefully be gone.  
 
 
I must stress that this tool will not fix all black screen issues. There can be many causes. But if your black screen woes began in the last 2 weeks after a Windows update or after running any security program (including Prevx) to remove malware during this time then this fix will have a high probability of working.  
 
 
If you Google Black Screen then you will find a whopping 80Million plus results, mostly dominated by people searching for a fix to this problem. Thousands of users have resorted to reloading Windows as a last ditch effort to fix the problem, avoid that at all cost. We hope we can help a good many of you avoid the need to reload.  
 
 
By the way - the cause of this recent crop of Black Screen appears to be a change in the Windows Operating Systems lock down of registry keys. This change has the effect of invalidating several key registry entries if they are updated without consideration of the new ACL rules being applied. For reference the rule change does not appear to have been publicised adequately, if at all, with the recent Windows updates.  
 
 
In researching this issue we have identified at least 10 different scenarios which will trigger the same black screen conditions. These appear to have been around for years now. But our advice is try our tool first. If it works great. If it doesn't you are no worse off.  
 
 
Good luck.
