After I start up my laptop and and access my account my laptop will freeze but I can still move the mouse around only I cant open any programs or select any icons. Also a white haze appears over the windows start up bar at the bottom of my screen. Previously I would wait a 5-10 minutes and get a notice that said windows explorer is not responding. I am no longer getting this message. When I press ctrl+alt+del nothing wil happen then my screen goes black, 5 -10 minutes later I will get a message that says logon and security operations were unable to be displayed when ctrl+alt+del was pressed. .I have tried deleting background programs like antivirus(malwarebytes and sophos) and other programs my university requires me to access their wifi to see if my laptop would start up faster.Before I am able to do my laptop freezes. If I manage to get a program open before my computer freezes, a white haze will appear over the program.Eventually i will get a notice that says "This program has stopped responding". About 5-10 minutes after that all the icons on my desktop and also the window start bar at the bottom will disappear and only my desktop wallpaper will remain.
I have a dell with a model number of PP40L and an intel duo core processor.
Thanks for the help
