Hey guys, so I just built a new PC and I'm running into a problem with my computer shutting down then rebooting when playing graphically intensive games like Witcher and GTA V. Everything runs fine for normal use (browsing web, watching videos, etc.) but I cannot play for more than 10 minutes before everything goes black and I see the boot screen. I currently have a gtx 980 and i7 4790k (both stock clocks) as well as a maximus vii hero mobo (all drivers installed), 2 sticks of 8 gb ram, and a Corsair HX 1050w power supply (about two years old).

I've read online that this problem is mostly because of either a wattage or a heat issue. Problem is my temperatures are perfectly within the "safe" range while gaming, and my psu should be able to handle my components easily. The last thing I wanna do right now is spend a few hundred bucks on a new psu, so I'm trying to rule out other possibilities first.

If anybody could help me out with this, I'd really appreciate it. Internet searches are not helping and I'm running out of options. Thank you.

1. make sure the mb has the newest bios file to rule out a bios bug.
2. in the bios make sure the ram xmp is on and ram is set to use that speed.
3. download msi afterburner set the fan on the gpu to man and turn the fan up to max and se if you hear the fan max out. if it is working then set a new fan profile to max the gpu fan out at 50-60c and see if the system stays up.
some time the gpu video drivers dont ramp the fan in pace witht the heat and some stock cards in some games can over heat. if your 980 card is a overclocked card try setting it back to stock speeds with msi see if the gpu chip is one of those that got binned wrong.
4. use a after market program to log your power supply voltages...check in the bios make sure th power...

Thanks for your help, I'll try what you suggested. By the way, do you know if decreasing the paging file size could be the reason behind the crashes? I changed it from the system managed size to 512 mb in order to free up space...
