Strange behavior after logon.
Hi there, I have installed Windows 7 7000 on my Vaio FS760 laptop flawlessly all drivers worked ok. After about 2 weeks of instalation a strange thing started to happen. Every time a logon in our out my domain network and with different users it just pops-up a Explorer windows like I've typed Win+E. All the screen remains black and this window stay and nothing more happens, then I type CTRL+ALT+DEL invoke the Task Manager and just a few process are running [4 process] and explorer.exe is amongst them. So I click "new task" and type explorer.exe, OK and voila. The initialization process starts like it shold be after I've logged on the machine. Does anyone saw something related to this issue. I haven't found anything that helps on the forums so far.Thanks in advance and, i have to say it, this Windows 7 is GREAT!!!MarckOliver

Does this happen if you login/out again as the same user? or only when you switch users?If you run msconfig.exe, is there anything unusual in the the Startup tab? Joe

Hi, Before moving on troubleshooting, could you please take the following steps? 1. When the computer works fine, change the theme to a non-Aero theme, such as Windows 7 basic or Windows Classic. 2. Restart the computer to test the issue. Does the issue re-occur? Thank you for your cooperation.

Thanks for your replies guys and sorry to take so long to respond.@JoeThis happens every time I login with any users. Now I have tryied with a user that never logged on my machine and it pops up a message saying "Location not Avaliable" and complain about a reference to a location [The profile location, I believe] that is not avaliable or is on a network share, but this user I've tested never logged on my machine and when I press OK the same Explorer window pops up. And the are no unusual processes lurking around my Startup tab.@RobinsonI've tryied what you have suggested and it behaves the same way regardless the theme I use...Thank you guys for trying to help me out. If you find out anything please let me know. For the time being I will just invoke the task manager and run explorer.exe manually.[]zMarckOliver

Does this happen when you logon with a local computer account? It sounds like something that is running in a logon script may be causing a problem. Logging on locally will help to determine if this is the cause.Kerry Brown MS-MVP - Windows Desktop Experience

The next step is start disabling startup programs with msconfig to see if a startup program is causing the problem.Kerry Brown MS-MVP - Windows Desktop Experience

Well, that's the thing. After the password the explorer window opens and the computer doesn't run anything from the Startup Tab. The only process that are running if I do not start explorer manually are:CSRSS.EXEDWM.EXEEXPLORER.EXE <- From the Window that is opened.RUNDLL32.EXETASKHOST.EXETASKMGR.EXE <- From the task manager opened to start explorer.exe again.WINLOGON.EXEIf I leave the computer alone it does not start anything else but these programs.Thanks for your efforts.MarckOliver

Did you already checked for possiable spyware, viruses, malware..etc?Also try to uninstal the videocard driver / software....reboot and check

Once Explorer is running then run msconfig and selectively disable items on the Startup tab. You'll have to reboot after disabling each item to see if that is the one causing the problem. The quickest way is to first disable everything on the Startup tab, reboot, and see if the problem goes away. If it does then start enabling items and rebooting until you find the problem application. If disabling all the items doesn't help then re-enable them all and post back for the next troubleshooting step. It's a lengthy process but there really isn't any shortcuts.Kerry Brown MS-MVP - Windows Desktop Experience

Everything that covers the basic funcionality of the computer is already checked, I'm using the videodrivers from the W7 itself [GeForce Go 6400 prerelease WDDM 1.0], should I try the NVidia Drivers. Virus and things like that I don't think is the problem since I'm using the Kaspersky AV 8 Beta for W7. Thanks for your reply.

Ok Kerry, I will try that right now and post the results as soon as possible. thanks for your time.

Yes try the original Nvidia driver for your GeForce Go 6400. supports of course windows vista but it will work fine on 7.Its a bit painful to remove the windows 7 video driver coz you have to disable the automatic driver installation, stop the automatic search for drivers for my hardware. login into svae mode and try to uninstall all the WDDM and the controllers then restart and install the original one.Are you not thinking about resotre point any how?Cheers
