this morning when i was trying to free my computer of too much cpu usage,using the ctrl-alt-del thingy...(dont know much about computers) i accidentally terminated a svchost.exe. (system) so now i think that it was the audio one so i need help on how to turn it back on and when my computer is starting up, it doesnt work. the toolbar at the bottom of the screen flickers on and off and each time it comes back on, it has to load all over again. is there a possibility of fixing this??? p.s. i am currently in safe mode on Windows XP on a Compaq Desktop. thanks....
