I fired up my rig to play saints row earlier.

I used to play the game all the time but havent used the machine for 2 weeks.

After 10 minutes the game quit, and the machine shut down.

The machine then tried to start up for a split second and then turned off.
Then after 20 minutes that happened twice more.

Ive now flicked the switch on the PSU.

all at stock
2500k
2x 7970
ocz 750w
watercooled, temps ~40c

remove a stick of ram at a time first and try that, and if you have a spare psu try that.

oh and a cmos reset, there the three things i could think to try prior to attempting to take gfx cards out.

this rig has been working fine for ages, im confused as to why this would have happened all of a sudden?

Maybe dust has settled after leaving it off for so long and causing a little short circuit somewhere?

When you say "Game quit and then Shut down", do you mean the game just exited, so you was on windows and then the computer shut down (as in if you was doing a shut down?) or did it just shut off?

Old psu?

I too would say PSU....

The game exited, the desktop showed up for a second and then the machine shutdown

Ive had it for about 2 years but it has had very little use.

Maybe 5 months of continuous use.

Hmmm...in that case, I doubt that's the cause.

If it won't turn on now it's the PSU

Gregster · 2 Nov 2013 at 21:39

I would be very surprised if it is the PSU. I have had a faulty OCZ before and that just powered off totally, no exiting screens or warnings.

I would run each card separately and see if it still does it.

Have you cleared cmos,battery out for 5-10 minutes?

Could be cold boot issue seeing it hasn't been powered up for a while,usually memory voltage/setting related

It did it quite nicely which makes me think that it isnt a faulty PSU

The best i could do is disable crossfire tbh, taking them out when watercooled is impossible as theyve got a solid EK bridge

No I havent but that will be my next course of action if it still refuses to work

Its really strange as this mobo has been rock solid for years and it used to sit unused for 6+ months when i was at uni and then turn on first time no issues at all

I would say PSU as well but that might be clouded by the fact that the only OCZ PSU I have ever owned died within weeks of use, so I regard them as junk and buy Seasonic based ones now.

My only other theory would be your pump has died and the system shut down as CPU hit protection mechanism and now it won't start because it's not picking up pump rpm on the cpu header?

Could it be possible that the game exceeded the psu capacity and it did a safety shutdown?

the pump doesnt have an rpm line so its not to do with that

mmj_uk · 2 Nov 2013 at 22:25

TBH I would have expected it to just cut out but with faults anything can happen I suppose, maybe it sent a voltage spike and the board detected it and shut down or something?!? I think modern Asus boards have surge protection although I'm not sure about other vendors.

I would check the pump just in case anyway in case it's died and the CPU is overheating, although if it was that you'd expect it to boot after 20mins or so switched off.

panyan · 2 Nov 2013 at 22:30

Ive no idea whats going on with it tbh, Im going to clear cmos and try again

If the problem persists i might try a new psu

Gregster · 2 Nov 2013 at 23:45

Do you not have PCI-E lane switches to turn them off and on? I can switch mine off and on so I have just 1 lane being used instead of both.

Edit:

I don't think you will have sorry bud and yer, for the sake of taking down your loop, not worth it.

If you can grab another PSU, that would be ideal. At least you could rule out the PSU being the problem.
