I hope this is the correct forum, I assume it is CPU related (Could be a hard drive thing though). If I am trying to extract a RAR file (3+ GB) everything else (web browsing, opening music, opening folders) runs slow or not at all in some cases. Running Win 7 Pro, Phenom I X4. Any ideas? I figured with a quad core I would be able to multitask a little more than it is currently letting me.
