Black Desktop Only Mouse Windows 7 64bit

I have a Windows 7 64bit Home Prem... After entering a password, just a black screen,  I can open task manager and even run some programs.  I even responded to a question and launched Internet Explorer.

Help ... I'm stuck!

it seems explorer.exe seems damaged run CMD from task manager then sfc /scannow

If you can open Task Manager, then first try this:  in Task Manager, use the File menu, then choose New Task (Run...) from the menu, type explorer.exe in the dialog box that opens up.  If explorer is not damaged that should start up the normal Windows 7 interface, with your desktop, taskbar, start button, etc. showing.

The SFC completed normaly and the windows.exe says it cannot be found.
LeeTutorretiredCommented:
What do you mean the windows.exe says it cannot be found?  What cannot be found?  Explorer.exe?  If so, then it sounds like either your hard disk is corrupted or you have been attacked by malware that deleted important system files.  If you have a Win7 DVD, then you can try going to the Command Prompt section of the Recovery Environment (choose Repair your computer when you boot to the DVD) and then run CHKDSK.

Lee,

Yes, Explorerer.exe.

I already thought of that and did so... even chkdsk /r.

I even checked and Explorer.exe is there.  Still nothing.

I ran a rootkit from Shopos and nothing.  Cant run ComboFix, not supported.  I just started running MalwareBytes.

Hmmmm
LeeTutorretiredCommented:
Seems to be a lot of hits in Google for this type of problem, and often it is a display adaptor problem.  This page from Microsoft seems to have some pretty good advice:

vic45708Author Commented:
Yes I understand ... the difference is I can run programs and I have a mouse.  I cannot launch explorer.exe.  

Do you know a way to reset permissions globally in the regestry to default?  Or even the WINDOWS directory?  The problem is remenicent of locked or denyed, registry entries or windows files.

If I don't find something soon ... it will be quicker to wipe and start over.

LeeTutorretiredCommented:
You may not need to "wipe and start over".  Since you can get into Windows, you could try a repair install, by referencing the setup.exe on the DVD using Task Manager:

I will try ... let you know.

Thanks!
vic45708Author Commented:
OK ... I never made it to trying the reinstall.

I allowed MalwareBytes to finish and just as I had expected, it found a bad Registry Entry.  I allowed MB to remove the entry and upon restart I now have a desktop.  I am going to keep the question open until I am comfortable that the machine does not relapse.  It's late here and time to call it a day.

Thanks,

Although I have my Desktop Back, what ever caused this problem left other problems.  My AVG no longer works and after Uninstalling it and reinstalling it the Firewall is DEAD.

I will probably need to ReInstall.

I used to use AVG, then I tried Avira and Avast.  Finally, I settled on Microsoft's Security Essentials (free, like the others I mentioned.)  You might be interested in this review from the SevenForums:

Lee,

Those products are GREAT for personal use.  I deal with end users, mostly small businesses.  I promote the fact that we should make sure that the companies be renumberated for their products.
