Having really strange issue with my PC.

**UPDATE**..
If anyone sees this and can help, my problem listed below has evolved.
I just got a replacement Power Supply back from Thermaltake, and after wiring it all up, hitting the power button the PC powered on quickly, without a problem. This only lasted for about 10 minutes however, then it shut off again. And would not restart for 15 minutes or so. The only way I was able to get it to boot up was removing the CMOS battery, which let it it power on, and boot into Windows. It crashed again after 5 minutes or so, and started rebooting, shutting off, and continuing until I just shut off the Power supply using the switch on the back. . . What the heck is going on with this PC? All the components are new, it ran for 2 months no problem and I'm not overclocking at all at the moment as I've reset everything to default settings... Please if anyone has any advice that would be great, otherwise I'll be taking this PC apart and sending everything back to be replaced as I have no idea what the problem is at this point.
thanks...

Hello, so I'll just get straight to trying to explain the issue I'm having..
When I go to turn on my PC and hit the power button, the fans and LED lights come on for maybe half a second then everything goes off. Then I have to wait maybe 15 seconds before pressing the button will do anything again.(I've noticed a green light on the mobo by the Power switch pins that goes off when button is pressed and then comes on again before I can press the button). In order to turn the PC on I must press, and hold the power button for about 20 seconds before the PC will boot. PC boots great after that, until I try to play a game. It is stable when doing wordprocessing, and handles stress test programs for hours and hours with no issues of any kind, temps are all great, but once I try to play a game it completely shuts off when I get into the game...
This issue started only a week ago, right after I beat Shadow of Mordor. I've updated BIOS, clean install of my ATI drivers, checked connections to my board, I am coming here hoping for some help diagnosing my problem. Hopefully someone can help.
I am overclocked by 10% on RAM and CPU, it's been that way since day one and has been super stable, temps never over 75 on CPU and the graphics card never gets near 65 C...
System specs:
Intel I7 4790K, OC to 4.4 Ghz
16 GB G skill ram at 1866
4Gb Sapphire r9 270x
Asus Z97 Sabertooth Mark 1 (SSD, Mobo, Graphics card, RAM and CPU are less than 2 months old)
120gb Kingston SSD + 1tb seagate hdd
Asus wireless PCI N15
PSU is thermaltake 850 watt... (2 years old)

Sounds like a power supply problem. I would say borrow a decent PSU from a friend or a store and try it.

Sounds like when you are putting your system on high load (Games), your PSU is not being able to keep up with it.

I'm going to borrow a PSU tester later this week from a friend. I have no way of getting a hold of a new PSU, and I don't want to buy one until I know it's the issue. . .
