When you restore your system back to the new factory settings, it will wipe your hard drive clean and do a fresh install of the operating system with the original factory setting.

To start this process, unplug all extra devices from your computer

(printers, external hard drives, etc.) as these can interfere with the system restore.

Starting with Windows XP, most systems with issued a system recovery disk in case of any problems with the factory installation.

Check the documentation and disks that came with your computer to determine if you have one of these system disks.

If you do NOT have a copy of this disc, skip to step 3 for further instructions.

Once you restart your computer, a screen will appear with the words.

Press Any Key to Boot From CD. Once you press a key, a screen will come up containing instructions to format your hard drive and restore the original factory settings.

Follow the on-screen prompts to finish the installation.

Once the restore is complete, remove your Recovery CD from the disk drive so that your computer does not try to boot from the CD again.

Restart your computer to complete the restore.

Unplug all external devices and restart your computer.

When the loading screen comes on with the Windows logo, press Alt+F10 together five times.

This will bring up the system restore menu.

hello hershyhunk to fully restore a PC to factory settings/defaults you will need to reinstall the operating system. to do this you need your recovery disks that came with your computer.
WARNING!! All of the data on your laptop's hard drive will be permanently erased when you restore it to its original settings. Before starting the restore process you may want to save any data you still need to an external drive such as a USB flash storage device.
Depending on the specific brand and model of your laptop you may need to select different options to restore the computer to its original settings. Check the manual that came with your laptop to find the specific menu options you need to select. Some computer manufacturers include an icon in the Start menu for restoring the laptop to its original settings without having to use a separate recovery disk. Double-click the icon and follow the instructions on the screen to start the restore process.

1. Place the operating system recovery CD that came with your computer into the CD or DVD drive. Restart the computer.
2. Wait for the computer manufacturer's logo to pop up on the screen. Press the keyboard key that brings up the recovery menu, which is usually "F2," "F8," or "Ctrl" and "F11" pressed simultaneously.
3. Select the specific language you want the operating system to use from the menu at the top of the screen. Select "Next."
4. Choose the option labeled "PC Restore," "Repair Your Computer" or something similar. Click "Next."
5. Select "Restore" and then click "Enter" to start the process. Click "Restart" once the process has ended to boot the restored computer to its operating system.

Turn the computer off.
Turn the computer on, and look for a message like "press BLAH to enter System Recovery".

Or, if you have a set of "System Recovery" CD/DVD disks from HP, then insert the 1st disk,
restart your computer, and select to boot your computer from the CD/DVD drive.

Or, there may be software already on your computer that lets you "burn" a set of "System Recovery" CD/DVD disks -- have 10 CD-R disks, and 5 DVD-R disks -- you may need to use most of these "blank" disks.

First, you need to find the original installation disks that came with your computer. There's a Dell System Recovery disk that will wipe your computer and reinstall everything as if it had just come from the factory. Insert the Recovery CD, restart your computer, and press F11 or F12 to access the boot menu. When you get the boot menu, select the CD/DVD ROM drive as your boot device. This will lead you through the re-install process.
