How do i restore my computer back to the way it was when i bought it?

Do a system restore.

Press the pearl or windows/start.
Program

Select a date when the program was still in your computer. Launch the restore. Let it restart by its own. Check if it's back.

Let me know if you need more help.

Thanks!

In this tutorial, I'll show you how to restore your Vaio PC to it's factory settings. In other words how to restore your computer to it's original settings (in the exact state you bought it).
For that you have to:
1. Back-up all your data. Restoring to factory setting means to erase all data and reinstall Windows, drivers and preinstalled applications. If you have a single drive (C:) you have to backup your data to external drive or disks.
2. Start VAIO Recovery Center. Click on Start button and then click on All Programs. From the program list select "VAIO Recovery Center".

3. Restore complete system menu. From the left menu of Vaio Recovery Center select "Restore complete system"

4. Start button.

5. Select "Restore C: drive" and hit Next.

6. Read the information on this new window, select "I understand" and hit Start.

7. "Are you sure?" If you made backup for all your data and really want to restore your Vaio as it was when you bought it you have to make sure that have it plugged in to a stable source of energy and press YES.

8. So ... next you should sit back and relax. Your computer will start showing the next messages
Shuting Down
Windows is loading files ...

Please wait a moment while Windows prepares to start for the first time...
Windows Vista setup: The initial setup may take up to 15 minutes. Do not turn off the computer. Click OK to continue the setup process and wait until the "Set up Windows screen appears". Select OK

9. Take your time until your system install VAIO software

Finish to restart.

10. That's all. Now, your VAIO has the original operating system, drivers and software. Now you have to configure your VAIO as you want.

In order to restore your toshiba, you will need the restore disks that were included or that you created when you bought the laptop. Make sure all your documents and personal data is backed up because once you start the restoration everything will be lost. The computer will be exactly as you purchased it from the store.

Insert the first restore CD/DVD into the laptop and restart the computer. It should automatically load but if it doesn't, let me know and I'll talk you through how to get the computer to load from your CD Rom first.

When you bought your computer, it came with restore dvds for your operating system. If you insert them in your computer while booting, a menu to reinstall Windows should come up.Just make sure to back up your important files.

When did this start? Do you know if you have a restore point saved from before this started? If so try doing a restore back to when you know the computer was working properly.

that would depend on the operating system that you have on the computer.. if u hav a windows xp operating system.. you need to run the system restore on your computer back to the date where you got it or not exactly on the date you got, probably a few days after you got it.. computer have save points.. your going to use the save points to restore your computer.. take note, new installed software or new items saved on the computer may be removed or deleted on the system.. the computer will go back to the old setting that it saved on that save point..

You should check the "my computer" window to view the avaible hard drives. You may have a hard drive partition call restore or something close to that. If you do, then restart you computer and look for an F key number to press for restore. This will allow you to restore the computer back to an Out of the Box state.

Call the manufacture and see if they would be willing to send you a restore disk. Also not a cheap way but you could by new windows xp and re-install it. System restore could get you pretty far back but it doesn't allow you to re do the whole hard drive. What is the operating system?

You should have everything saved ("backed up") on dvds now. Your next step is to pop in the restore discs that came with the computer unless you have a vista machine that isn't a toshiba or dell because vista machines (like HP) makes you create your own.

pop in your disc, boot to cd, and press next a few times... it will delete everything and get the pc back to the first day you bought it.
