I just bought the ASRock 990FX Killer Fatal1ty AM3+ motherboard and the AMD FX-8350 CPU yesterday. I already have all of the other parts which some were from my previous computer. These are the parts:
RAM: 8gb Corsair Vengeance 1600
PSU: Corsair AX760
Graphics: (2x) MSI R9-270X in crossfire at 5992x1080 resolution
Cooler: Corsair H60
SSD: 60GB OCZ Agility 3 (boot drive)
HDD: 250GB Toshiba SATA III (storage drive)
OS: Windows 8.1 Pro x64

I don't have the system overclocked. Whenever I play Guild Wars 2, Skyrim or World of Warcraft for 5-10 minutes, it just reboots. No blue screen, nothing. My three monitors go black and it shows the ASRock logo and it boots. Can anyone shed some light on the situation? Thank you.

Did you do a clean install of Win 8, or just plug the old hard drive in? if so, differences in drivers & hard ware could have caused this.
Can you boot in safe mode?

I did in fact do a clean install of windows 8. I only had the SSD plugged in, and I booted to my ODD which had the windows 8 disk in it. I deleted the previous partition, so it's a clean install. I can still use my computer (I'm on it right now) I just can't game on it.

Do you have anything to monitor the temps? (like hwmonitor)

I just monitored the temps, and under load the CPU hits around 45C and the mobo hits 28C. MSI Afterburner reports that the graphics cards are hitting 65C. That isn't enough to cause a reboot though, is it?

One other thing, while the memory 'matches specs' it is not on (that I see) Asus QVL list, inspite of specs, it is also not uncommon to see unexplained issues from memory that hasn't been tested by the mobo mfg.
