I want to reeboot my windows xp
That is both EASY and FUN!.... if you have all your stuff.
Before you do ANYTHING. Make sure you have all your discs. You need the Operating system disc (usually green or purple, says DELL on it). And you need your DRIVER DISCS. (usually blue or black, and there are usually 2-3 of them).
Now, Assuming you have these discs, here is what you do first. login to your machine and look around for files, pictures, documents, etc, and MOVE them to MY DOCUMENTS. Next, take your flash drive.... (if you dont have one, shame on you! those little buggers are NEAT!) and slip it into a USB port, then OPEN the my documents folder. Once youre in my documents, click EDIT, SELECT ALL, then click COPY. now, minimize that window, and go to MY COMPUTER, and OPEN the flash drive (usually E: or F:), then click EDIT and PASTE. Your flash drive (hopefully it is at least 8 gigs) will store your files, pictures, and documents. This will take awhile so go make a sandwich, watch a movie, go on a date, take a nap ,etc.
Once that is done, shut down the machine and remove your flash drive. Now, LOOK at the computer, for a sticker that has the windows XP KEY on it. you NEEEEED this key!!. Without it, you do not legally own windows. Write those numbers down, you will likely need them later.
Start the computer and insert the DELL WINDOWS XP Operating system disc, and boot from the CD. (you can press F12 at the DELL screen then select CDROM drive to boot from).
Windows will begin loading the windows setup. (its a blue screen). Follow the prompts till you see something that says to delete the partitions on the disc. Delete the C: partition and re-create the C: partition, and install windows on it. You will choose QUICK FORMAT NTFS, and then you are off and running. Windows will load the OS from your disc. Just follow the prompts and answer the questions (such as what time zone, computer name, etc). FYI: Computer name can be anything, HomePC, YolandaF, insp6000, anything. You will likely be prompted to input the key, but, since its a dell disc on a dell machine, you might be able to skip it for now. Follow the prompts and answer the questions, and it will complete in about 2 hours.
Once the windows has been reinstalled, get your dell discs and reinstall the device drivers (sound driver, video accelleration driver, usb 2.0 driver, etc etc etc). That will take another few minutes, but luckily, the Dell discs can detect what hardware you have, and install the drivers you need. (they will have a Check beside them). Just go down that list till all the checked things have been installed, and your pc should be back to factory.
Next, register with microsoft to activate windows. Since that key is valid on that box, you should have no trouble. If you do, just call MS (they will give you the 1800 number) and you can read the key, and they will complete the activation for you.
The end result will be a computer that should run just like the day you got it, if not better.
