Why does my computer restart when trying to switch users?

Windows restarts when second user logs on.

We have a shared PC at home and whenever someone else tries to log into their account, and someone is already logged on, Windows is just restarting, rather than letting the second person log in. I have tried Google but I can’t even find other people having this problem.

I have a fairly new (less than a year) Toshiba PX30t All-In-One running 8GB and an i7-4700MQ.

Any ideas would be appreciated.

    Thanks to you both, I did a clean boot, didn't seem to make a difference.

    I did run the sfc cmd and it threw 4 errors in the WinSxS folder. This lead me to do a search and I found a result where the guy had the same errors. He was told to run DISM /Online /Cleanup-Image /RestoreHealth and it fixed his sfc error output. Which did the same for me. Still crashing.

    System is up to date, and Malwarebytes, Kaspersky and MS Essentials have all come back clear.

    I don't have a suitable level/version of Windows to access gpedit either.

    I will see if I can wade through the system log to see if that identifies what the problem is.

      UPDATE: Just loaded the BlueScreenView and it is showing BAD_POOL_CALLER for last crash.

      BAD_POOL_CALLER is there anything else like something.exe...

      This may or may not be related, but both Kaspersky and MS Security Essentials are real-time scanners and you should not have more than one installed and running at the same time.

      BlueScreenView should not only display the error name but also where the error occurred. It will be given as memory locations within a program file (.exe or .dll).

      Thanks
      Bruce my bad, I didn't run essentials on the PC with the problem, I ran it on another one (trying to do too much at once and getting my stories overlapped).

      I didn't dig deep enough with BSV, it identifies NetgearUDSMBus.sys I will investigate what that is for and see if it is an easy remove or update, then update this post.

      I will have a look at Driver Verifier as well.

      they have the same problem, uninstall the Netgear USB Control Center - check to see if it will fix the problem? other perhaps you can update it if updates available.

      Thanks to all. I jumped in and tried the Driver Verifier without checking up about it and, of course, it fragged my system. DRIVER_VERIFIER_DETECTED_VIOLATION was the outcome, and system wouldn't boot.

      Used recovery USB but wouldn't allow roll back to any of the Recovery Points or Back Up Images. Unspecified Error message which looking up on another computer said was something to do with security software???

      Was able to do a Refresh, and I am downloading/updating to 8.1 now, will take several hours for this to happen. So (hopeful) this will fix my problem by default. I won't install the Netgear app.

      Will post an update once I have gotten through the next couple of days.

      okay wow, sorry to hear this, i think if the Driver Verifier (DV) finds a violation it will result in a BSOD.... Recently i had a similar problem couldnt use restore point or backup image, i had to boot on windows cd and format the hard drive then boot again on Acronis true image live cd and use the image to restore. But now you did refresh this will fix almost all problems. Not installing NetGear USB Printer Control Center apparently can be the source of the problem is recommended.

    Fred,

    Windows Event Viewer creates a log entry providing detailed information about system reboots. Assuming that you're correct and the operating system is gracefully rebooting and not crashing I would first recommend making sure that Windows is up-to-date and that your system is free of malware. Use an up-to-date anti-virus/anti-malware and remove any items list as unwanted. Finally, use the Microsoft System File Integrity Checker to verify that your Windows Operating System installation is error-free.

    If the above doesn't resolve your issue, tell me if disabling Windows fast-user switching resolves your issue. Make sure your restart your computer after making changes to the operating system for accurate results.

    Does this resolve your issue Fred? Please let me know.

    if recently you got remote control session and not closed properly then this can cause problems.

    first try sfc /scannow

    A clean boot helps eliminate software conflicts, maybe this can explain your case if you installed some applications
