Problem solved: Windows 7 slow on dell notebook

Ever since I installed Windows 7, my laptop was very slow. Whenever I ran vlc, I had to close all other applications to save it from dying down. I solved the problem with my Windows 7 being too slow. Well, it is a long story: I had a dell notebook which when charged its battery full, would disconnect the battery and run the laptop on direct power. Due to many problems, I got it replaced, but the new laptop (1521) lacked this feature of disconnecting the battery. As a result, my battery wore out after 2 years, while the earlier laptop's battery was good even after 2.5 years of use. Since we always use the laptop at home, I let the battery inside and use it as desktop replacement. A few days back, when I turned my laptop on, it said that my battery was almost dead and thus my computer could run slow. Walla ... that was the reason. I removed the battery, and the laptop now runs fast, much better than Vista. (however, not when I run Vuze) :)
