I've had my new rig running most of the day, but earlier on I left it unattended for around half an hour and when I came back to it it'd turned itself off.

When I turned it back on it turned itself off almost immediately, restarted, turned itself off, restarted, turned itself off and then restarted.

When it finally stayed running my monitor didn't recognise it and stayed in power saving mode and the mouse was unresponsive. It wouldn't turn off by using the case power button or the motherboard's.

I turned it off at the mains and waited a little.

I turned it back on at the mains and it immediately turned itself on again, was totally unresponsive, so again I turned it off at the mains.

I reconnected it to the mains, turned it on using the motherboard's power button, and then almost immediately it turned itself off again and then turned itself on again.

Power buttons again were useless.

I turned it off at the mains.

Turned it back on at the mains. And then used the power button to turn it on.

It's been running smoothly now for an hour, and I've made no changes.

What the hell is wrong with my rig?

It's been running fine all day, and was running fine while browsing the internet just before I left it to its own devices for half an hour.

Anyone have a diagnosis?
 
Everything connected snug and tight.

Corsair AX850 PSU, so no lack of power.

CPU running at 29 degrees idle.

I made some adjustments in the BIOS in the morning to overclock my 2600k to 4.7 in turbo boost, and ran a stress test on it at 100% usage for 2 hours without any problems whatsoever. The CPU stayed stable at around 59 or 60 degrees too.

Upon one of the start ups following the restarting debacle the American Megatrends stuff came up and told me there'd been a failed overclock or something to that effect and to press F1 to enter the set-up. Which led me to the BIOS.

I didn't change anything in the BIOS and just exited into windows after another restart.

It can't be anything to do with overclocking as besides the stress test it's been running at 1.6mhz all day in idle. It was certainly running at that while I left it unattended for a brief while.

Just to add, on one of the many occasions it booted up and was nothing but a powered up corpse the DRAM Led light was on, not flashing but on.

I'm not sure how significant that is as it went away after the next restart, but nonetheless I thought it could prove relevant.

Thanks for any help.

I'm assuming you have a P8P67 board, that's a common issue - as you said though, you don't need to change anything.

As to the actual problem, I've no clue D:

P8z68 v pro, mate.

Is it a common problem?

So it's not indicative of a fault with the motherboard etc?

And if it is a common issue, when is it likely to strike, could in the middle of a game be a possibility?

Just happens on boot up. Not sure about the Z68 boards, but I know it's common with the Asus P67 ones - could be the same thing.

Does it happen frequently, or is there something which makes it more likely to do so?

Also, is it across the board, or just some users who suffer from it?

I'd have thought if it was so common there'd be more unrest about it, but whatever.
 
It sounds like a power problem to me.. Possibly with the PSU or the VRMS on the motherboard.

Before you do anything, make sure the BIOS settings are on "Fail safe" settings thereby eliminating any OCing issues and retest. Testing should be done using a Prime on full load.. Use System Monitor to watch the temperatures. This is a base test so if it passes then you have a working system.. It must be your OC. If it doesn't then you do have a fault somewhere else.. Where the temperatures ok during the base test?

Check the PSU is supplying a good and stable current.. Follow my guide here:

If the PSU looks ok, then it's looking more like a Motherboard problem.

Before you come to that conclusion, make sure all your front panel connectors are secure and in place. Making sure they aren't shorting. You can jump start the PC by using a flat end screw driver just to see if it fires up ok thereby eliminating any FP connectors.

Try removing and testing the build outside of the case to eliminate shorting issues.

Check the Event Manager for clues. Event manager is often overlooked and under estimated. Goggle any errors.

Lastly, as Stulid says, possibly flash the BIOS but check any warranty conditions first.

Good luck
 
All temperatures are fine, and the PSU isn't an issue either.

I've had no problems today as of yet, but from everything I've read it appears to be a motherboard issue.

Whether or not it's a common problem across all normally functional boards or a hardware issue I've no idea.

Could anyone advise some software which would test run the system in order to pick up any errors or faults?
