How can I reset my emachine w3653 to factory setting? Unfortunately, I forgot my password. help

Hi! Normally the emachine came with an eRecovery Disk that you can use to restore the PC back to factory settings. To do that follow this steps:

1. Press F2 to enter BIOS Setup during Power-On Self-Test (POST while the eMachines logo is being displayed).
2. Using the keyboard arrow keys, arrow over to Boot.
3. Refer to on screen instructions to set the first device to CDROM.
4. Press the CD-ROM drive eject button and insert the System CD.
5. Close the CD-ROM tray.
6. Press "F10", then press "Enter" to save the changes and reboot the system.
7. The computer will boot from the eMachines Recovery Media, follow the prompts to reinstall the operating system.
