GA X79-UD3 spontaneously shuts off

[nick_m]

Hello forum,

In the past 5 days, my computer has spontaneously shut down 4 times. The first 3 times, it happened within 5 minutes of booting. Today, it happened after 6 hours. It doesn't enter a power-on loop, it just shuts off. After that, the power button starts the computer normally.

I've had this computer for 2-1/2 years, and aside from some occasional boot issues, it's been trouble free. I have an i7-3930, 32 GB RAM, NVIDIA Quadro 2000D video and 2 each SSD/HD. The PSU is 700W.

Can anyone suggest a diagnostic tool or procedure to help me figure out why this is happening?

Thanks,
Nick

I would first unplug PSU then remove battery for no less than 10 minutes then boot it up and set bios to the specs you had. Report back after that if it still does it.

Make sure it is cleaned out of dust bunnies also.

Thanks, autotech,

Is there a way to dump the bios settings to a file prior to battery removal, so I can restore the setup?

when you update bios it gives you the chance to save bios to file. I guess you could enter the bios flashing tool in bios and instead of flashing it just save it then quit. Kinda defeats the purpose though if it a change you made to bios that is doing it or  a part you installed.
