How To Reformat Your Windows Computer


Reformatting Your Windows Computer Should Be A Last Resort!

Reformatting your Windows computer is usually the absolute last resort and might even be unnecessary. Before you go through the process of completely reformatting your hard drive please take a few moments to read through the rest of our website. If you are reformatting to fix problems with your Windows computer it's possible that by using some of the tips on our site, or by downloading or purchasing some of the tools or products that we link to, you might be able to avoid the need to reformat your computer. Because doing a complete reformat of your computer will erase the contents of the hard drive and require you to reinstall all software, reformatting is usually a last resort.

Some Computer Manufacturers Make Reformatting Easier Than Others

Many name-brand PC manufacturers include a restore-disk which makes it easy to reformat your PC and return it to the state it was in on the day you purchased it. Some manufactures supply only a standard Microsoft Windows CD, and some (usually lower-end PC manufacturers) supply nothing! If your computer did not come with a restore disk or reformatting CD, then you will need to take extra steps to format your hard drive and get Windows re-installed.

Back Up Your Files Before You Reformat!

Because the reformat or restore process erases everything on your computer, it is critical to have a backup of any important files on your computer. You will also need your original software install disks, install keys, etc to reinstall any software you have purchased.

 

Things to do before you reformat your computer:

  • Write down or print out all notes and internet pages because once the format process begins, you will no longer have access to them (or anything else in the PC)
  • As already stated, BACKUP all important files and data! When you reformat your computer everything will be erased!  You do not need to backup your software, because you should have those CD's or you can usually re-download it.  The important things are photos, music, documents, checkbook files, etc
  • Make sure you have all the CDs and other software. All programs will have to be reinstalled after you format the hard drive. Don't forget about software that came with hardware such as printers, scanners, etc.
  • Write down the brand and information for all the hardware on your computer. Look in the Device Manager and make note of the brand and model of network adaptors, video cards, sound cards, printers, modems, and displays. After reformatting you might need this information to reinstall drivers.

I have no idea what that even means.. But i am able to decipher that your Windows is messed up.
Generally, you can do 3 things when Windows breaks, ranging from simple, to a major pain:
1) try simple file repair utilities like CHKDSK
2) try a "windows repair"
3) do a full reformat and reinstall

For more/better help I would ask that you create a new post, with full details of what, exactly, you were doing, and what, exactly, happens now when you try to boot, including error messages, etc.

What the heck?! You didn't want to lose your work so you restarted? That's like saying "I didn't want to run out of gas so I filled up my car with boulders and drove up to the mountains" OMFG ..

As Hubby said, you probably need to reinstall Windows. He also asked you to start a new thread/post for more/better help but it seems you don't follow directions well. If you can't boot up to your Windows Restore Disk then you need to read your manual and find out how to make it boot up from that CD drive. If your disc is not recognizable or bad, you may need to buy a new one or get a replacement from the manufacturer. If nothing in that drive is recognizable, you may need a new CD drive. There are probably many other issues and things that can go wrong that you will also need to figure out along the way. If you don't know how to deal with these things you might need to purchase professional help.

Query
My drivers are on my F drive. Do I need to have them on an external disk? Well, for now my computer does not copy paste things. That is why I am going for this formatting. So I can't copy my drivers on to a CD. Please help

Re: How To Reformat Your Windows Computer

If you dont have a recovery CD or Windows installation CD, you wont get everything back.. Actually, you would have difficulty even doing the reformat without downloading something to do the formatting with.
If your compurer is relativly new you might be able to contact the manufacturer and get a free or low-cost recovery CD set and/or Windows CDs.. Otherwise you will have to buy them.
If you have to buy your CDs it might be worth a trip to the local computer shop where they can sell you the CDs and do the whole reformat and everything for you.

Re: How To Reformat Your Windows Computer
this guy is wrong. Now adays you don't have to have a cd, as most computers no longer come with restore disk. as far as getting anything back, it depends on what you're wanting back. when a reformat is done, your computer should be as it was the day you originally got it from the store. if you're reffering to personal files, then you either need to back them up or take the loss.

Re: How To Reformat Your Windows Computer
Your computer was probably originally made for a different operating system... Such as windows vista... That could be one reason you cannot hear any sound, i had the same problem myself. Or you may need to buy a new audio card made for windows xp.

Re: Device Names before formatting

My 9 month old or so Laptop is giving me a Graphics driver has stopped responding and has recovered error a while ago. It's been a while since it has come back up but just today it did thus limiting what applications I can feasibly run. I don't really want to reformat my laptop but see it as the best solution as it will also clear any other problems for a longer period.

I've got two recovery discs that came with the laptop, one being for the OS (Windows 7) and one named "Application and Support Disc" which I'm guessing includes all the software that it came with including drivers, would it still be recommended to take down all the device names?

Many Thanks

Re: Device Names before formatting

Hopefully it won't be necessary, but if it turns out you need an exact device name after formatting, it will have been well-worth the 4 minutes you spent writing them down.

Format computer

Try the free version of MalwareBytes (http://www.malwarebytes.org). It can probably remove whatever you have.
if Malwarebytes fails, or you just want a clean-start, then doing a reformat or 'restore' will surely cure it but remember that everything will be erased. I'm going to go out on a limb and guess that if you havn't kept up your antivirus, you havn't been doing backups of your critical 'cant live without' stuff either?

.. if you are going to use Windows (as opposed to a Mac) you must use an antivirus. Mac or PC, you must backup up anything you care about.

Re: Formatting a Windows computer

YES...
this is why it is important to have a backup of everything.
Be sure to backup all your "data" - this is the 'stuff' you have created such as documents, photos, music, videos, internet favorites etc
Be sure you have your original software discs to you can reinstall all of the programs you have. you dont need to worry about 'backing up' your software, because you should have the discs (or info to re-download if you downloaded from somewhere)
If you use 'web based' email (ie you go to Google.com or yahoo.com for email) you dont have to worry about your saved email. If you use outlook or some other email program that stores your email on your computer, you will have to backup those emails - how you do this depends on your email program

BUT...
When you use your Windows disk or manufactuers "restore" disk, it will first reformat your hard drive (erasing everything) and then it will re-install windows and everything that makes your computer run - the same as it was the day you bought it. This means that as soon as your computer is back up and running, you must then re-apply all of the windows updates and security patches, the very first thing you do.

IF...
any of this makes you feel uncomfortable, or if the 'stuff' on your computer is life or death, "cannot lose at any cost", then you may want to consider paying a few $$ to the local computer place to do it for you (anyplace but GeekSquad who will simply rape you based on my experience). My next door neighbor services his own transmission but no way i would try doing it myself based on instructions on the internet.

Reformat computer before selling
If we are selling our laptop and we want to wipe the laptop clean of everything, would you suggest reformatting?

Re: Reformat computer before selling

YES - either reformat, or use the manufacturer's 'restore' CD (if they gave you one); or better, check out DBAN (dban.org) to really "nuke" it.

Re: How To Reformat Your Windows Computer

When you format, you do it by partition (drive letter); so if you format drive C:, EVERYTHING on C: is erased, format drive D:, everything on D gets erased, etc.. if you do a system restore (from the manufacturer), or Windows reinstall, IT may wipe "everything" (all drives) but will usually give warnings - it is very important to have backup's of anything you care about at all times, not just when about to format.. and READ, UNDERSTAND, and follow the prompts and messages when doing the reformat/reinstall.

Re: How To Reformat Your Windows Computer
Hi, my old laptop kept coming up with the "start windows normally" screen.No matter what option I selected there was no response. I rebooted from the recovery disc which came with it and it starts fine with what I would call a very basic windows screen. No wireless or anything. but I can't access whats on my C:drive. It's like it has a separate drive altogether. I know the stuff is still on there because I can access it through "My Computer". I've tried to reformat but it won't do it. It just goes back to the windows screen. Any suggestions. Thanks
