How do I change the hard drive? I bought a refurbished computer and the drive that came with it was corrupted, so the company sent me another hard drive.

The context does not provide specific instructions on changing the hard drive in a Dell OptiPlex 790. However, in general, to change the hard drive in a Dell OptiPlex 790, follow these steps:

1. Power Off and Unplug – Shut down the computer and disconnect all cables.
2. Open the Case – Remove the side panel by sliding or unscrewing it, depending on the chassis type.
3. Locate the Hard Drive – Identify the hard drive bay inside the case.
4. Disconnect Cables – Unplug the power and data cables from the hard drive.
5. Remove the Hard Drive – Unscrew or release the drive from its mounting bracket.
6. Install the New Hard Drive – Secure the new drive in place and reconnect the power and data cables.
7. Close the Case – Reattach the side panel.
8. Power On and Configure – Turn on the system and ensure the new drive is recognized in the BIOS.

If reinstalling the operating system, boot from a recovery media or installation disk.
