My computer randomly shuts down instantly. It even happens sometimes in the bios. And sometimes it runs for days under load without any problem.

I checked and it is not a temperature issue.

What I'm wondering is if it's somehow possible to log what caused the instant shutdown. I was thinking that only the motherboard could log it since sometimes it even happens when in the bios.

My motherboard is an Asus p8p67 pro rev 3.1.

The BIOS is unable to log something like this. It sounds like a hardware issue. – Ramhound Sep 19 '12 at 15:55
@Ramhound, some motherboards have a limited amount of space with which to log certain events. Unfortunately this is not one of them. If it did, it may help since the problem is obviously hardware related. – Synetech Sep 19 '12 at 16:02
@Synetech - All those events happened outside of the operating system. Once you boot into the operating system anything that will be logged would be logged by the operating system. – Ramhound Sep 19 '12 at 16:13
@Ramhound, yes I know, and Monster clearly said that the problem happens while in the BIOS as well, so it’s not a software issue. – Synetech Sep 19 '12 at 16:20

The motherboard will not keep logs like this.

This sort of failure could be caused by RAM though. Run memtest from overnight and see if it throws up errors.

The other thing it's likely to be is a power supply on its way out, but this is harder to test without installing a spare.

Outside of that, you could see if there's an updated BIOS you could flash.

thanks for answer but i am looking for motherboard level solution. because only it can help me – MonsterMMORPG Sep 23 '12 at 22:24
I'm afraid what you're trying to do cannot be done, at least not on a consumer grade motherboard. – Miles Hayler Sep 24 '12 at 8:37
well that definitely sucks. putting 10 mb memory for logging error text would not hurt the manufactures – MonsterMMORPG Sep 24 '12 at 20:02
I completely agree and think this would be a great idea for the future, but alas not this time! – Miles Hayler Sep 26 '12 at 16:30
