Cant find out why PC shutdowns during gaming

[HunkUmbrella]

I did read on reviews. Some of the people are having the same problem. They are say when it hits 70c the computer crashes. If I'm reading this right "GPU Temperature('C)". Then the card is running at about 70c/158f. That is way to hot.

Yes the card does get good reviews but you might have a bad one. Now thing is some of the cards do come OC. Did you try to under clock a little just to see if help. Some of the newer cards don't need as much power as the older ones.

Well before GTX 980 I had GTX 690, and it was fine running on my old PC, but when I bought new hardware - motherboard, PSU, RAM - it starts to shutdown even though, GTX 690 started to overheat and died in the end, the same happening with GTX980 now.
And yes I am lowering my GPU clocks specially trying to prevent shutdowns minus 228mhz GPU and mem clocks and full fan loads by using EVGA Precision.
Still this is not an solvation, cause in service my GPU run at 65-70 during game test and all was fine.
It will be too bad if it is PSU, cause this ICE Hammer cost me much and now buy another one, damn.

This problem seem the same to me, the guy solved it by changing PSU, maybe you guys give me an advice wich PSU to choose from these:

Are you still having the "open driver handle failure"? I had this problem, make sure you have full admin rights to "gdrv.sys". Worked for me.

Power Supplies...  I like Corsair or EVGA.  While there are others out there, I've on a few rare occasions had to deal with warranty/replacements for clients and once for my Father.

In my experience, these two vendors have stood behind their products "1000%".  When something fails under warranty, people usually don't care why, they just want it replaced.  That's exactly what I've seen from both of these vendors...  I'm here now after 13 yrs with Asus exclusively. Their warranty is a joke.

It's not the RAM. RAM is RAM. This is 2015. If the motherboard supports it and it's not defective, it will work.
It's either the PSU or the GPU.

Is it possible you may have an electrical short between the motherboard and case when you replaced the board?
You could try it out of the case to rule that out.

Where are you guys getting the idea that 70c on a gpu is too hot?

The default Fan Profile in Precision will attempt to keep the card at 80C under load.  Although the card can handle more, it will become unstable unless a custom fan curve is set since heat will continue to accumulate unless good positive air flow and case pressure is maintained.  The system seems to be "bouncing" around. I don't think we know if his card was ACX or reference design.  Probably doesn't matter.  Reference design is better for case with low airflow or SLI.  ACX good for case with good airflow "pressure".  My pref is 80c under load.  After discussion, I think everyone decided it was his PSU.  Problem could be resolved, but we don't know since there was never a follow up or resolution posted.

Snip...
I know this. Point is more than one post insinuates you guys are all " ermagerd 70c, there be problems fer sure"...when that's rather typical load temperature.
Besides, it's probably the PSU.

[Slimreaper]

It's the PSU probably. "Icehammer"? Seriously. Never heard of it.

That's a load of crap. 70c is not that hot.
