My computer has been running extremely slow for the past month, and I have no idea why. When I open Taskmanager, it says that there is 100% cpu usage, and that the "SYSTEM" process is maxing out. I am not running any programs, and is slow from startup. I've ran adaware, and anti-virus software, but all came up clean.

Make sure you anti-v & spyware remover is up to date. Run them from Safe Mode. Don't just depend on AdAware...download/update/run Spybot-Search & Destroy too. And be sure to Immunize.

Also download & run CCleaner to clear out all the internet garbage & other junk files.

You can find all those programs & more, here:

to ad to jams not also go to start/run type msconfig and hit ok.

Go to the start up tab and uncheck the items that don't need to be ran automaticly when windows starts up. If you don't know what programs do what go here and type in each startup item in one at a time this will show you what startup items are running all the time.
