It's as easy as inserting the recovery CD your computer came with and restarting.Is there a way that you can completely clear off your computer at home?
You can reformat your hard drive with the recover cd that came with the computer. Or you can buy a new operating system Windows XP, Windows Vista, or Linux installation. Linux is absolutely free and has more free software than you could ever imagine.
If you have windows, this is the solution. If you still have the disk that came with your windows, like an XP disk, then pop it it, restart your computer, and (i think) press F5 until it says it's booting off of the disk. Then wait until it loads. When done, there should be something that says partition disk or reformat or something like that. Press the button that it says to press for that option. It will either give you the drives that you have on your computer, or it will give you 2 options, quick or normal. If it asks which type, quick or normal, than you should choose normal. Normal takes about 4 hours, but clears your entire drive, so that it's all empty, or you could choose quick, which takes about 1 hour but doesnt clear the entire drive, it leaves some things behind. If it asks which drive, choose the hard drive you want to clear and press enter. It should now be working on your computer. It should be introducing you to windows while it reinstalls itself. It will ask you for a serial for the windows that is getting reinstalled, which you should have on your disk case, then it will ask you simple network questions about your speed and how your internet is set, like wired or wireless. When its done, the drive you chose to reformat/partition/CLEAR =)... will be...cleared. Remember, windows only reinstalls if you cleared out the drive that had windows installed on it, but if you install it on a drive in which windows isnt installed on, than you will still clear the drive, but windows wont reinstall. I did this, but i did it on windows XP, so i dont know if its like this on vista or MAC, but for sure it's like this on XP and lower. If you need an installation disk, go to google and type in your windows and then torrent, so it should look like this as an example but without the quotation marks -- ';Windows XP torrent'; -- but you need torrent software. For that, go to google and type in '; bitlord';, ';bittornado';, or you can use limewire, but it's slow there. Hope this LOOOONG tutorial helps you out.
well i did this not on purpose. i was trying to fix my computer and so i shut it down a unplugged it. well that seemed to work because everything was gone!! or you can just clear everything.
It depends on what you mean by clearing off, if you want to start with a clean slate then format the HD and use your disk to reload if you have one or use the recovery system on your pc...If you are have problems with the pc you may want to do a system restore to a time previous to the problem. If you plan to sell or give away the computer you may want to use software such as window washer to overwrite everything several times then reload windows. be warned formating takes a lot of time with large hard drives and windows xp or newer..........
