I am a PC noob so I dont know nothing about it. My PC is terribly sluggish and laggy and GOD know why is that. I dont know its configuration. I have just seen i5 printed on it with 320 GB drive. It's a Samsung laptop with windows 7 that came pre installed.

I want to get my laptop back to factory settings. I used to do a similar restore on my old Nokia device. Is that possible on windows?

Help me out guys..,
