Task manager acting wierd

Today I was about to start up FSX and opened up task manager to see if i could close any unnecessary processes, so i Ctrl+Alt+Deleted and this happened....


Its really strange and I dont know what to do! The only way I was able to close it was to restart my computer... I can click on the processes but I cant go to the "end task" page.... Any help would be much appreciated!
