PC shuts down when playing games :(

[MrTomnus]

I was hoping I could get some help with a problem I've been having with my PC. I've had it since February, but I only got my graphics card this Monday.

I've been playing some games on it, and occaisionally it will just switch itself off completely and restart. There are no Windows error messages on restart. It could perhaps be a PSU problem, but it's a 750W EVGA supply which is more than enough for my parts... Here are the specs:

i5 4670k at stock clocks with CM Hyper 212 EVO

8GB 1600MHz RAM

MSI R9 290 at stock clocks

Seagate 1TB HDD

Kingston 120GB SSD

Windows 8 64bit

I will post temps during gameplay when I get home, but from looking occaisionally while playing in the past the CPU stays at 50 celcius +-5 celcius and the R9 290 is at about 70 celcius. I'll run temperature programs while I play tonight and if it happens again I'll post the log before the shutdown.

Does anyone know what the cause might be? I have updated everything and I'm running catalyst 14.2 drivers from AMD.

Double check all of your power connectors are snugly in place. I had that issue a few times with my 780ti. I had thought it died halfway through doing some benchmarks and then I realized that the PCI power cable fell out

check the seating on your 212 EVO, i had a similar issue with my H100i, but that was because my pump wasn't connected to the sata properly, this can be caused by an overheating CPU, as protection, so yeah try reseating your cooler.

im guessing the pc was ok before the 290 if so try a different pcie slot maybe in the process if the upgrade you might have broke the slot or try a different PSU

I might try that later, I've got work soon It hasn't happened again yet so if it does then I'll swap it. I don't have another PSU unfortunately...

Checked, and they're fine

The cooler is fine as well!

It could just be one of your components. Unlikely the video card, but could be the motherboard or power supply. I've also seen those kinds of things happen with RAM, too. Don't worry though, Corsair has a lifetime warranty on all of their memory. Also, try a different pci-e slot and see if your video card is still under warranty if thats the problem.
