A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

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.

CD/DVD reader/wroters are 'generic' parts, so any that the right size (5 1/4" or 'slim-line') with the right connector (IDE or SATA) should work OK. If in doubt, just buy from Dell (at their rip-off 'spare part' prices)

To get the Optiplex case open, look on the Dell web site for the 'service manual' ..

During power on, you should see a message like 'Select boot device' or 'Set boot order' or some such .. typically you press F12 ...

Alternative you can set a 'permenant' boot order in the BIOS (press F2 during power-up, as I recall)

you could try replacing the power supply. if it still does not work, you probably fried the processor or motherboard. (or both). just make sure the replacement power supply has the same type of connectors on the power leads to the motherboard, hard drive, etc.
