Hello! Ok let's see... Suddenly my computer has suffered severe slowdown. I'm definitely sure it's not a virus, as I scanned with malwarebytes, and also avg and no such malicious material. (also i've not been on dodgy sites) Anyway, I notice severe lag when running my firefox browser. Opening a tabbed window with a youtube video loaded, and trying to use yahoo/msn. Even with only one window open (let's assume two tabs), and msn messenger open, the computer spazzes out and freezes. I notice this happens more with a youtube video running. Anyway I've never had such severe slowdown before... and I guess the only change I can think of is upgrading to the new firefox version. It gets to a point where the computer is unable to terminate processes, so I have to restart. Anyone have any suggestions to help my pc become less of a resource hog perhaps?
