remote procedure call terminates unexpectedly

[manny]

Every so often this messegae pops up, ''the remote procedure call has terminated unexpectedly and the system must shutdown". Then it gives me a minute to save my work. Also in my task manager, the CPU usage is at 100% even when I'm not running anything, what is going on?? Can someone help me?

Are you using XP? if so it sounds very much like the blaster virus. Does it only happen when you are connected to the internet?
If it does then get the patch from the Microsoft website.
I am not sure about your CPU usage problem.
