To Flash your BIOS in Windows it is recommended to do a few things first to ensure a successful flash:

- It is recommended to Reset the BIOS to defaults before flashing. Simply go into the BIOS and restore to defaults or clear the CMOS.

- If in Windows Vista or later - Disable UAC in Windows as this can sometimes conflict. (Control Panel > User Accounts > Change User Account Control Settings, click and drag the slider down to "Never Notify" and click OK, then you MUST reboot for this take effect.). You can re-enable this later if you use this feature.

- If running a software firewall or Antivirus, it would be recommended to temporarily disable that or set to lowest possible use to avoid conflicts.

- Disable any background running processes, browsers, etc.

To Flash the BIOS manually:

First download the latest BIOS from our website ( https://www.evga.com/support/download/ )
