For about the last week or two my computer has been running very slow. Today I checked the Task manager and the cpu usage won't drop below approx. 50% and spikes higher sometimes than that. This is all happening with out any processes running showing any use. Other than occasionally the SVChost.exe, system idle, system & my firefox when its open. Please anything you can suggest would help. I just did notice there is 6 svchost.exe processes. Is that normal?
