If the machine truly operates normally after you restarted from this, it may have been a glitch in exiting and may be nothing to worry about. <br />
<br />
If you are interested or inquisitive, shut the machine fully off and wait 60 seconds. Power up and enter BIOS by F1 or enter or whatever DELL asks you to do. See if it happens again.

Thanks, John. I'll try that later. (BIOS entry is via F2 on this machine.)

Tried it again and it hung again.

Hmmm, &nbsp;this is the machine with the Windows 8 install problem as well. <br />
<br />
You (we) cannot troubleshoot a BIOS issue - BIOS either works or does not.<br />
<br />
So you may wish to contact Dell Support about this machine.

test if by removing the AC cord + the bios battery for 20 sec - then replace them - if it gets better

I'd suggest flashing the bios with the latest firmware and testing it again. It's unusual for a system to hand at that point. &nbsp;It may be caught in diagnostics or when writing data to CMOS. You might try replacing the CMOS battery if nothing else resolves the issue. its an low priced test that may work. <br />

Hope this helps!

@eschamp &nbsp;- I had said earlier to call Dell Support and to replace motherboard. So the answer you accepted was the SAME as my answer earlier.

Oops! What can I do to correct that?

@eschamps - I have reopened the question and suggest you split point. The other answer was also good, but there were two answers, so just split. Thanks.

I have the latest BIOS version.<br />
<br />
I F2'd into the BIOS/UEFI so I could configure it to boot from the optical drive before an internal HD. That worked bit when I hit &quot;Save and Exit&quot;, the machine froze.<br />
<br />
Had to cycle power to get it to reboot.<br />

What could be wrong?

Dell XPS 8700 Hangs on &quot;Save and Exit&quot; From BIOS

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.

Desktops

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
