i started getting ths error randomly about 1 week oago. happens whether i am using pc or idling. i know what the service is, and how to restart it, but i want to know why this is happening. i am also getting errors from windows search service, saying that it has stopped. i have installed no new software and have done a clean install and anit virus sweeps. i am running vista 64 ultimate, with all windows updates installed, and sp1 installed (happens with and without sp1). also, does anyone know if there would be a performance penalty if i permanently disabled these services? this is not a work machine, strictly gaming and internet, sometimes some recoding, but not too often anymore.
