Hey guys,
I'm sorry for another post like this, all I see is posts with this type of problem so I have been reading a lot of threads about this kind of issue, I tryed a lot of stuff and fixs from the community but no luck, my problem seems to be a little different from most users like overheating and psu problems etc...

So I will start with my rig:

I have a 2600k OC at 4800ghz wich is beeing cooled by a push/pull h100i from corsair, temperature seems fine, arround 68c full load under intel burning and prime95, I tested for 8 hours with each software.

Ram: Corsair Vengence 1600mhz 2x 4gb, I tested this for 2x8 hours once with intel burning (ram test) and Memtest in dos. No errors found.

PSU: Corsair Ax1200w, I test it with another PSU corsair hx1000w and the shutdown still happens.

GPU: EVGA GTX690 temperatures go arround 73c under full load, fan at 95%. I have tested with a spare, a very old card GTX275 and random shutdowns still happen.

Motherboard: Asus Maximus IV Extreme-Z. (don't have a spare MB to test) but voltages in bios seems fine don't go over the 5% range.

This problem is getting very hard to pinpoint, strangely enough this only happens while gaming and seems (can't be sure) to happen when I'm alt tabbing from a fullscreen game and desktop.
Yesterday I had a two hours gaming sessions in Witcher 3 and no shutdowns, today while playing LoL I alt tabbed to windows to check a steam message, then alt tab again to the game and boom, computer shutsdown.

Also shutdowns are instant and the computer powers on after 1 second.

I'm running my rig in a full updated windows 8.1 and latest Nvidia drivers.


Some other checks I did:

I read that some people fixed this by changing electric sockets, so I try that but no luck...

I have also check my motherboard circuits to look for any damage in the capacitors, seems fine for the naked eye of course.

Updated mother bios to the latest.

Updated GPU firmware to the latest.

Rollback some nvidia drivers to some old versions and back again to the latest.


Stuff I didn't do yet, but want to:

Test my rig with another CPU and Motherboard but unfortunately don't have any spares...


I'm running out of ideas, I didn't want to buy new stuff this year, was hoping for a next year upgrade...

Hope someone can help me pinpoint this problem...

Thanks for reading.
