    Hello, I am having issues with the computer I built for my grandparents. http://speccy.piriform.com/results/BdOHfoWmZDbDeWQUSFD5LWv

    I will turn on the computer, reach the user login screen. There are 3 users to pick from. It usually doesn't matter which I pick. Sometimes this issue will occur sometimes it won't. There are 2 different variations of the issue. 1.) I will click on a user to login to but no password prompt will appear, just the mouse and the blue flowery looking background is present. 2.) I will be able to input a password but the desktop fails to load and all that is present is the mouse and the spinning circle with Welcome next to it.

    The only way I get out of either issue is to do a manual shutdown. Sometimes I can login without and issue. I've found booting into Safe mode, rebooting from safe mode then attempting to login allows me to login, but I have no idea whether or not Safe mode has anything to do with it.

    I hope you guys can shed some light on my situation. Thank You

    Update 1: I have ran Memtest86 for a pass and a half and received no errors. I've also attempted to do a system repair, and sfc /scannow. https://www.dropbox.com/s/pa97zzruxo5mk2s/sfcdetails.txt

    Memtest needs to be run for at least 8 passes to be any where near conclusive.

    I can see in the Speccy report you only have 4GB or Ram and it is all in the same slot so it will only be running on a single channel, performance should improve if you put another matched RAM stick in the other channel so it will then run as dual channel.

    The Speccy report also shows every voltage, including the CMOS battery, as being a long way off from what it should be. I do suspect this is a misreading as the system would be unlikely to run at all if these readings are correct. I would check the reported voltages in the bios and post them back here.

    Finally the SFC scan results show a problem with the TVEncDec manifest which is corrupted. The best way to fix this is to run a Repair Install: Windows 7 Repair Install

    I ran a second sfc scannow and it returned that there were no problem files that needed to be repaired. I can extract those specific files if I need to but it looks like that is no longer an issue. I believe the issue is resulting from something around the winlogon.exe executable since that is what handles the login process. But I'm not sure how to find that out.

    Maybe event viewer will help with that? But I'm not sure how to read event viewer very well. I'll look into getting a second stick of RAM, thanks for bringing that to my attention. I'm not sure how to fix the low voltage issues, I didn't know that was a problem. I'll re-edit this post here in a second with the BIOS voltages.

    Ok, sounds like some progress is being made.

    Winlogon.exe is unlikely to be a problem as the System File Checker would have reported an issue with it if it was not ok.

    Have you completed a full Memtest as I suggested, run it overnight and check the results in the morning.
