Dell Optiplex 780, user forgot BIOS master password (which is necessary to change the boot order to run BartPE from CD and do an image backup).

There is a jumper on the mainboard called PSWD1, which is set (shorted). Remove power cable from PC (CMOS battery can stay in place), open the lid. Remove jumper from PSWD1. Reconnect power, start the PC, hit F2 to enter BIOS. All passwords should be reset.

Leave BIOS, power off the PC, remove power cable. Reattach jumper to PSWD1, close lid, reattach power cable. Start PC. Enjoy.

Hey there, After doing some googling it seems that the default key for dell PCs to access the recovery partition is pressing CTRL+F11 while your computer is booting up.

I hope I was able to help.

Sounds like your on Google Chrome, this has started popping up since the last update and only on secure webpages at random, try running Windows Update and make sure it's up to date, it check the root certificates which should come with the windows updates.

ok 960 SFF is not the same as MT or the big case MOBO.
SFF has its own mobo (motherboards)
it has 11x2 row non ATX spec, power . not yours as it has 12x2 some SFF have 2 diffr. mobo
and a dell custom PSU for just this mobo and its odd duck jack. (called PICO plug)
why not buy a new PSU? that matches this PC?
even the SFF PSU case is not ATX spec.

Go into device manager. Uninstall audio driver.

Restart computer.

This will reinstall the default driver. Try again.

If it doesn't work, go to Dell website to find specific driver for your computer (using the service tag) and install that.

Desktops PCs usually have a 'jumper' on the motherboard, inside of the PC, that resets the BIOS, removing the password but also changing some settings to their defaults. It takes some 'know how' but you can google it to help you locate it.
