ok, i have had this problem with my cpu starting today. apparently it only happens when i get online whether my browser is open or not. i have dial up, so bear with me. any help is appreciated. after maybe 2 mins online a message pops up saying the following: This system is shutting down. Please save all work in progress and log off. Any unsaved changes will be lost. This shutdown was initiated by NT AUTHORITY/SYSTEM Time before shut down : (starts at a minute) Message: Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly. also, a window pops up SOMETIMES before the previous that i just typed saying: Generic Host Process for WIN32 services has encountered a problem and needs to close. so does anyone have any ideas on what in the hell is going on? it's making me kind of mad. it hasn't started this until today. please help!!
