i'm new to vista, i've just bought a dell laptop with vista home premium, it's a core 2 duo 1.6mhz with 1gb ram ,even if the laptop is sitting idle the memory usage is at around 55% ,i installed wow on it last night and it ran like a dog and the memory usage is up to around 92% , i have noticed that there are a lot of processes running around 70 and there are a few programs that i don't need, dell diagnostic software and stuff like that ,do you think i've anything to gain by doing a fresh install or should i just remove the programs that i don't need.
