I have experienced lately some high CPU usage and some unexpected crashes .First of all....No spyware, no viruses no malwares of any kind HDD's are fine, no missing files .By searching with google I came across with this fixing: http://support.microsoft.com/kb/890582 Has anyone ever heard about this? I filled up the form and after a couple of hours I received the following email form email@example.com: Hello, The hot fix for your issue has been packaged and placed on an HTTP site for you to download.

Any other suggestions on fixing high cpu?
