My computer has been reacting sluggishly for the last few days. It'll be fine for several hours after starup, but then it starts going very slowly when I open or close a program. I hit ctrl-alt-del and under processes cthelper.exe is at a sustained 94% cpu usage. I'm guessing it's part of the software for my audigy. Is there any really good reason to not take that .exe out of the startup so that it won't do this again?
