PC Shuts Down Under Load

Cooler is bolted in fine.

Just ran a OCCT PSU Test and the PC lasted 5 min before shut down.

At the time of shut down the CPU was at 100% load and 59c, Gfx card was at 89c and 98% load.

So I dont think its a temp issue.

Is there anyway I can create a log in OCCT to see if there is any voltage spikes?
 
Think I might have found a cause!

Just ran another PSU test and that seemed to last a long time without fault (yey)
So I thought I would run a GPU test as thats whats being hit more when playing games.

The TMPINO was climbing steadily and I quite the test just before it hit 100c! Could this be the cause of the shut down?

Am I right in thinking thats the NB? I had to remove all the cooling pipes from around there in order to get my old (dead) cpu fan off. So could possibly need resitting.
 
Checked all the heat sinks on the motherboard and they are fine.

All fans are working fine and all temps seem to be ok.

I managed to sit on Dawn of War 2 for around 4 hours last night without any issues so I thought we might all be good. Until it shut down just as I quit back to windows lol.

I have run a GPU test through OCCT and the 480GTX lasted under 2 min before shut down all temps were as low as before.

Just put in my Wifes 260GTX and its currently running a GPU test and has been stable for about 35 min now. The TMPINO sensor hasnt gone above 85c.

Now the hard part is going to be working out what the issue is, is it the PSU thats not working or my gfx card?

I have a 500w Cooler master PSU I could use to test the 480GTX to see if that also causes a shut down on the GPU test as that would rule out the card.

Although I fear this might be an unfair test as it is the bare min for the card to run.

Any ideas?
 
I think its GPU problem, 100c is a time when everything crashes and you get bsod to save your system from burning itself alive. Take away overclocking on GPU and you should be ok and get compressed air and dust it.
 
Those cards are quite simple to remove the heatsink and clean actually as I had one. They didn't always run stable at stock clocks was the main problem. You may need to back off 20mhz or so on the core as they sold them very highly overclocked with not much headroom. You could try a different TIM on it too.
 
The 480 heatsink is new as the card just got back from an rma due to a fan dieing a couple of days after my old PSU lol so only issue would be how they've fit it.

Going to try the card in my bros rig as he is running a 1200w PSU so that should rule out the power issue lol.

What's the best way to lower the clock speed on the gpu?
 
Right think I have put this to bed.

tested the card in my bro's rig, ran solid as a rock.

Just tested my PSU and Gfx card in my wifes rig (just has 1 HDD and 1 CD drive) runs fine in the stress test.

Put all the gear back in my PC.

With 1 HDD the stress test is stable
With 2 HDD the stress test is stable
With 3 HDD it shuts down under 20 seconds.

From this I am guessing the PSU just isnt producing the goods.

could well be PSU - but also HDD not being able to cope - try putting that HDD in another PC - if possible, as testing it.
 
Sounds like a heat/stability issue to me, sorry if i have missed it but have you tried running cpu at stock for now, (presuming you have it oc'ed)
 
If TMPIN0 is the motherboard and hitting 100c there's your problem. You removed the cooling pipes. They are included for a reason as few people have active cooling over their motherboard.
 
Looks to be sorted guys,

Would appear I have done a school boy error. I daisy chained the SATA cables up to the HDD's (worked fine on my old enermax psu) after giving each HDD a seperate cable it all works fine up to 1000 seconds on the stress test and temps are all within the 40's!

Thanks for all the advice going to rinse some BF3 this afternoon to see if it is stable to game on!

Great job pinning it down :)!
Out of interest, is that just because the PSU couldn't cope with 4x/3x on one cable?

I'm intrigued as I have 3x on my AX750.
1x SSD
2x 1B each HDD
