Windows 7 rebooting after login

Having issues with several machines we just running Windows 7.    Our users enter the login/pw, it starts to load W7, but then logs off.   I had the user log into Safe Mode OK, but when they try it under a normal login, it goes back to the reboot loop.   Any suggestions?

Boot into Safe mode and see if a temporary profile has been created. This happens sometimes with Windows 7. Use Profile Management (Computer, Properties, Advanced) to delete any temporary profiles.

Also make sure Windows 7 is properly activated. This symptom above will occur if not activated.

Take a look in event viewer for some errors or warnings logged.

I also should have noted:  See if you can run System File Checker (SFC /SCANNOW) from a command prompt in Safe Mode.  ... Thinkpads_User

I've had them run the SFC with out any luck.  The Event IDs that are common to users are 1084 ShellHWDetection.

Check one of the machines thoroughly for malware (try malwarebytes). Windows 7 is quite reliable and this is not normal. Did you check Activation? ... Thinkpads_User

Machine is activated.  No temporary profiles.

Traditionally, the immediate logoff is a bad Userinit value here....

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

It shouold be set to "C:\Windows\system32\userinit.exe,"

But Safe Mode wouldnt work.....

Since Safe Mode works ok, then I would start here.....

Perform a clean startup to determine whether background programs are interfering with your game or program

Start with the Satrtup Tab, and then the NON MS Services....

Do all the machines have something in common - like nvidia graphic card?

When nothing is wrong, it is time to take one of the machines and reinstall Windows 7. If the machines are name brand, use the Recovery Partition and bring back to factory setup. If you built the machines yourself, check BIOS, Chipset, Video, Audio and NIC drivers for the latest version and make sure you have those on hand.  

Rebuild one and see if you get the same thing. .... Thinkpds_User

sound more like a hardware problem to me..please check if you are using an onboard graphics card, you may have to set it to minimum windows 7 requirement. (at least 64MB) and check how big your RAM installed..

We discovered that our GPO was turning on the Application Identity service (Applocker).  Once we disabled it, the machine would log in.  There was a conflict somewhere.
