Need to factory reset hp dc7700 desktop

Launch the HP recovery application that should be installed on your computer. Then select the factory reset option. This will boot the computer into a small partition that will allow the computer to reformat and restore back to factory standards. Please note that selecting this will delete all data on your machine.

Accessing the recovery partition on your HP Pavilion laptop allows you to restore your computer to speed it up, eliminate a virus or repair your Windows operating system.

if you want to do the factory default setting then you need to install the operating system with the help of recovery cd's.

if you have the recovery cd's you need to connect the usb external cd/dvd drive to the computer.

if you don't have the recovery cd's you can get it from www.hp.com or you can call hp telephone support they will help you out.

1. While most Dell desktops respond well to "System Restore," which restores the Windows operating system, occasionally a computer may need to be restored to factory settings. This is usually done as a last resort and is usually due to viruses that can't be removed. While you should try "System Restore" on your Dell first, resetting the desktop to factory settings is an option. This is done through a PC restore by Symantec. Be aware that not all Dell desktops have this ability, and before proceeding with this option, you should call Dell tech support
   
   

2. Make copies of all things on your PC you want to save, such as photos, documents and other installed programs. Resetting your PC to factory settings will erase all data on the hard drive. It will erase anything that you installed on your computer after you received it.
   

3. Restart your computer.
   

4. As the computer is turning on, you will see a blue bar that says "Dell.com" across the top of your monitor. At this time, press the Ctrl and F11 keys simultaneously. If you wait too long, you will miss the opportunity to do this and will have to restart your computer again.
   

5. Click the "Restore" option when the next screen appears.
   

6. Click "Confirm." The PC will begin its resetting process. This process takes approximately 10 minutes.
   

7. Click "Finish" when the process is complete. Allow the PC to restart itself. Do not restart it yourself since it needs to run through its boot program.
   

8. Click "Yes" to allow the computer to restart. When it does, it will be at original settings, and you will see the "End User License Agreement" screen. Click "Next." The System Restore screen will appear, and the computer will do another restart.
   

9. Once it does another restart, click "OK." You have now reset your Dell desktop to factory settings.

Your compaq should have come with a factory CD that will allow you to restore the system.

Insert the cd and restart the computer. It should boot from the cd and ask you if you would to repair the installation (or something similar).

Without the HP CD you can pretty much hang it up with a copy of Windows.
