Hi, you can use your supplied discs to do this. Turn laptop on and then put the first disc in. This is not the driver disc. Turn the laptop off. Turn it back on and keep tapping F12 until there is a box on the screen for boot device selection. Select yur DVD drive and hit Enter. Let it load into the disc. If it comes up with "Press any key to boot from CD..." or something similar, then do so. Once it has loaded into where it requires your input, just follow the onscreen instructions. If you are not worried about changing anything or losing data, you have nothing to worry about and continue through all settings without worrying too much as you cant make your laptop worse at all. That should be it!
