This is just driving me crazy...
 
all was fine until now, old gear is :
 
I5-3570K at 4,200mhz
MSI msi z68a-g55
G.skill DDR 3 1600Mhz xmp.
PSU HX650W corsair.
 
3 weeks ago in games computer started to shutdown and restart. 
when it happens i always hear a strange "click" and then computer just shuts down + starting again.
 
happens only in heavy games like GTA 5 etc...
 
after a week and about 3-4 shutdowns mid game my motherboard was fried.
suspecting the PSU i decided to upgrade the whole PC.
 
new gear is :
I7-6700K (not overclocked- Stock) no point overclocking this monster.
MSI gaming M7 motherboard.
kingston savage hyperx 2800Mhx xmp (set at xmp profile of 2800)
PSU seasonic gold X-750w
 Driver 372.70 (updating to newer one but i don't think it will help)
started GTA 5 and after 40 minutes of gameplay BOOM i hear this strange Click again and before i realized what's going on computer restarted O_O.
 
CPU is water cooled and at full load hovering at around 50C (about 28C idle -  53C max)
GPU set to costume fan curve and never passing 70C. (fan speed reaching 75% at max)
Motherboard Temperature hovering around 40C.
using Fast sync and getting around 120-190FPS in gta 5 all maxed out.
also i hear buzzing coil noise from the GPU at high FPS with Fast sync or Sync off. (but that's expected and i don't mind this noise)
 
now i wonder, what in the name of great caesar ghost going on ??? is it the GPU ? i have swapped everything but that.
 
also like to add that i used EVGA GTX 780 for 2 years and i never had this problem. (computer was solid like a rock until GPU upgrade)
 
need help guys :(

Sounds like the gpu is the problem since you have swapped everything else out. Try using another gpu or running off the igpu for awhile.

when using Igpu nothing happens but then i can't really play games with it.
with 1080 if i do the same things as Igpu nothing happens.
the issue only happens when i play heavy games with NO V-sync or with Fast sync On .... strange but i think with V-sync on it never happened yet.
 
but then the games are slow and sluggish :S (V-sync sux)
 

Are you running your PC off a UPS?
 
I had a 6-year old UPS crap out one of my PCs.  When the PC drew just enough power, the UPS would drop power (even though it was well below the UPS power limit)...I would hear a "click" when this happened...the click was coming from the UPS.
 
I replaced the UPS with a new one and all is fine now.
 
If you don't have a UPS...have you tried a different surge suppressor?  These can go bad too.

Man this is 2 threads in a row.. drop the ups!

When I was 25 my old man helped me install a dedicated outlet just for my rig.. he was so terrified my huge pc custom overclocked monster would burn the house down.. anyways get a dedicated power line for it if your room can't supply enough juice for your rig.

Also good to note, when I had gtx 780 all was fine... That card uses more power then 1080

I actually meant the power cables from the PSU to components as opposed to the lead to the outlet.

after gaming in GTA 5 for 1 hour + monitoring Voltages + Temps + load etc... it's kinda strange.
PSU delivering power solid like a ROCK... and i mean on all rails... better then my old HX650w that fluctuated in V12 and so on. this PSU is very solid.(actually amazed by it's performance VS HX650w)
going to monitor this issue further and see what is going on in time. don't really like to RMA my new GPU yet.

Where is that clicking noise coming from? Is it from the PSU?

well, sadly there is no way to know.
even though PC is right beside me i can't really know were this click is coming from.
i can't listen and play at the same time... and even if i could i need to put my ear to GPU and play or to PSU and play. not really possible.

Very strange indeed... updated drivers and played all day along.
no restarts, no shutdowns.
i guess it was a driver ?
 
Things working fine, will update this thread if things go south in the future.
 
 

Hmm. Yes, please keep us posted.

For some time things worked alright...
Today computer shuts down mid game and won't start again.

After checking things out...
Pc wont start with gpu inside. Without its powering on with no problem.

After swapping gtx 1080 for an older gpu, pc working fine.
As soon as I put in 1080 pc won't power on.
Tried it In other pc and it's the same.
I wonder, is there a protection of some kind that prevents my pc from starting.. Can it really be the gpu?and if it is... How can I be sure for 100%?

Its brand new gpu :(

I see, I will rma my new gpu then. But still, I wonder... If there is a gpu fault of some kinda is there a protection that prevents pc from starting?
Asking for general info.

When my gtx 8800 died pc would start but there was no signal.

But now... Pc wont even power on with gpu inside the slot.
