I keep getting a problem that occurs more and more often. One of my svchost.exe processes keeps using all available system resources so my CPU usage is at 98-100% all the time for about an hour... It mainly happens after a bootup but it would then go away in 3-4 mins. But if I leave my system idle for hours, it happens and takes a lot longer to go away. A few times I've ended the process but then my sound would only half work and would glitch, so I'm guessing it helps control system volume? Sum1 told me my system registry could need to be cleaned. I don't know how to do that and don't know a registry checking tool that I would trust. Anyone have any idea on what this could be?
