This issue only appears when playing war thunder, and once in fm (kinda).Effectively it freezes, and shuts downs, but before it says my gpu crashed (latest drivers).Just right now my gpu crashed whilst playing war thunder, and when i tried to get in again the pc shutted down (sometimes it goes straight for the shutdown thing).
all parts are new.Is it some compatibility thingy going on with war thunder?
i checked both cpu temps and gpu temps and both never go above 65º-67º.
when it happened on Fm was a single gpu crash but all was fine afterwards

Psu-crossair Cx600
Cpu-i5 4670
gpu-asus gtx 760 top
Mobo-gigabyte h87m-d3h
Hdd-westen digital Caviar green 1TB
Ram-8gb (2x4)

sorry for any bad english

Having to recycle power to the PSU to get the system to re-boot, sounds like a problem with power. I suppose even a new PSU can fail.

You might also check that all PSU cables are firmly in their sockets. The 24 pin and 4/8 pin MB cables sometimes don't clip over the locking tab on their headers and the connection can come loose as the system heats up.

But if it only happens with that one game, that adds to the mystery. Can you try to MAKE it crash with some other games?

closest i got was a standard gpu crash on fm 14, bare in mind that the crash on WT only happens after 1 maybe 2 hour of gaming, nevertheless im concerned about it, after searching around it seems nvidea drivers and wt without vsync dont go very well together, ill try with vsync on and see if it fixes (fingers crossed)

If you're going to use vsync, use adaptive vsync.

Apparently vsync is not the answer. You could try rolling the driver back to a previous version. Are you using the beta?

im using geforce experience to keep my drivers updated, maybe shadowplay has something to do with it..?

Furmark 720p benchmark was sucessfull 4259 points, 70 fps average, and 72º max.

decided to check the connectors and apparently my 24 pin connector was a bit loose (no idea how it got that way).So i reconnected it and tried war thunder, lasted an entire round without issues.
hopefully that was the root of the problem.
ill preform more tests later and see if it crashes again
Edit:so far so good, seems like that was the problem all along, ill set this as solverd. thanks
