You need to know your PC brand and model to get drivers, if it's custom built, the motherboard brand and model and components used.
I accidentally remove the Intel Petium 4. And I hope there is a free download of it. Please help me. If whenever I got some CD of it, it will be useless, because our CD roam is broken and cannot be used.
Can you give some more details? You can't remove Pentium 4 - it's a piece of hardware. Does the CD ROM open when you press the button? Are you using that computer to post here?
