is someone trying to delete my system 32?

some people in a chatroom i go to got into my webcam and i had to disable it through device manager ... in chat they kept prompting people to delete sys 32 as it speeds up there system but i know what it really does. when i turned on my computer today it come up a black screen but still with the programs and icons on.. it said system 32 is either deleted or moved to a new location. i rebooted my computer and everything was back to normal just running bit slower. my regedit also i can't find i had to go in command prompt to open it up and it's only showing a program icon not the actual regedit icon.. are these script kiddies trying to delete my system 32 ????
