When I start up my laptop, windows 7 I think 64 bit, and it starts normally but after a second I cant click anything on my taskbar and I can click the start button but nothing in it. I cant right click on the taskbar to start task manager or press ctrl shift esc. When I press ctrl alt del it will take a couple seconds to load then the screen will go black and say that the logon process was unable to disppay security and logon options when ctrl alt delete was pressed. When I click any of the icons on my desktop it has the spinning circle as if its trying but then will give up. The problem started a couple days ago and I did a system restore to 2 days before it happened and it didnt change anything. I got avast and didnt find any viruses and I got a legitimate registry fixer/cleaner and ran both in safe mode and found about 360 registry errors and started up normally again and the same problem persists. If you need any other information to help me I will provide it.
