Hi guys. i am new to the finer details of computing so i will apologise in advance for my in-experience. I recently purchased a packard bell laptop from an old friend,the computer works ok. however it has information on it that i dont want,so is there any way that i can just wipe it clean? so its just like it came straight off the shelf? then re-install windows xp? Also some of the parts of the laptop dont work e.g speakers. ive heard about drivers that fix the problem but im not sure. can anyone help me? Thanks in advance and any help will be appreciated.
