Details please. Runs slow all the time no matter what you're doing? Or when you're doing certain tasks? What hardware, what OS? How much RAM [hugely important, that's a major factor in slow systems]. The more info you can give the more people can help. What EXACTLY are you doing that appears slow to you? Rendering 3D graphics, playing games, writing text docs, surfing the web? Detail details details. It's like taking your car to the mechanic and saying "it's not running well." What does that mean? Doesn't stop when you hit the brakes? Doesn't go when you hit the accelerator? The mechanic needs to know EXACTLY what's going on.
