when I started my computer, there popped out some warnings about system not running. After I closed them and rebooted my computer the first thing I noticed was that all the icons on my desktop were gone. Then after finding out that cmd couldn't find c:driver I took someone elses advice, just to find that right clicking on my desktop didn't react additionally when I press Alt+Crtl+del the Task Mannager wouldn't run, instead I get an error message saying the adminastrator had blocked this function. But I acctualy have adminastrator rights.
Any help is highly appreciated.
