Hello,
I have this problem with my laptop - sometimes I cannot login - after choosing the user the screen freezes or after logging in it works only for a few minutes in regular mode (I can do things over those minutes like open firefox, but I cannot open folders, sometimes I can open the task manager or even some programs) but then it freezes and I have to shutdown the computer manually by pushing the power button. When I tried pushing crtl+alt+del I got a message "The logon process was unable to display security and logon options when ctrl+alt+delete was pressed. If the operatin system does not respond, press esc or restart the computer by using the power switch". I don't know if this helps, but I try to add as much as I can. Sorry it it's not relevant - my knowledge about computers and IT is minimal.
The computer runs fine in safe mode.
So I tried system restore to a week before when the computer was still fine and it didn't work. So I reinstalled a graphics driver (Intel HD Graphics Driver) as I found on the internet that similar problems got fixed by reinstalled videocard drivers. And it worked, everything started to run smoothly again in the regular mode. As normally I allowed windows updates and after restarting my computer, the problems came back.
I assumed that the problem was the updates so I uninstalled most of them (KB2930275; KB2923961; KB2925418; KB2929755; KB2929733 and KB2918077) but the problem was still there and I was unable to uninstall the last update (Microsoft Silverlight 5.1.30214.0) so I did the restore again, but to yesterday before the updates. And it didn't help.
I ran CWShredder (didn't find anything), SpyBot (found some cookies and a few registry keys), but that didn't help either.
Do you have any suggestions what is causing this and what could I do about it? I would appreciate any help :)
My computer is Dell vostro, Windows 7, 64bit
