When I start my computer it ends up showing the task bar and the system tray and the desktop area is black. It says explorer.exe not responding. Well I just let it sit like that and about 10 hours later it loaded up and the computer was working fine. Of course when I shut down the computer and restarted it I had the same exact problem but this time it took 12 hours. It starts up fine in safe mode. I am not computer savvy but please help.
