I was happy when I finished configuring the newly-formatted laptop mentioned in this thread
Sound Driver for Toshiba Satellite A135-S4467
I've given it to its new user and everything looked fine except that Winrar wasn't working somehow! It looked like uninstalled but the shortcut in Start menu was still there! I don't think anyone had touched it by that moment except me.
I thought I'd reinstall it later, and this later time came.
I noticed that when I shut it down, it gets stuck at 'Save your setting' phase unless I force the shutdown by holding down the power button, and when I log on, it gets stuck showing only the mouse pointer and does not show the desktop unless I press the power button!
What could have happened and what can I do about it?
