I built this exact computer about 1 month ago:

CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor
Motherboard: ASRock Z87M PRO4 Micro ATX LGA1150 Motherboard
Memory: Patriot Signature 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Samsung 840 Series 120GB 2.5" Solid State Disk
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI Radeon HD 7770 GHz Edition 1GB Video Card
Case: Fractal Design Core 1000 USB 3.0 MicroATX Mid Tower Case
Case Fan: Arctic Cooling Arctic F9 43.0 CFM 92mm Fan
Power Supply: XFX 550W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply
Optical Drive: Samsung SH-224DB/BEBE DVD/CD Writer
OS: Windows7 Home Premium (Legit Copy)

The assembly went flawlessly, very straight forward and I spent a lot of time on cable management and making sure each component would have sufficient air flow and cooling. My core and GPU temps are fine under all conditions and I am not currently over-clocking the system at all.

During game play on Max settings for all parameters, at very non-repeatable times, my computer will freeze like its lagging, repeating the previous sound it made for the past ~1sec over audio and the screen will flicker with the same ~1sec repeat until I hard boot it off. It will continue until I force a hard-boot.

What is this^ indicative of? What sort of failure or problem would cause the system to repeat the previous sound/video from the past 1second until it is forced to shut down?

I have minimal things running and have a very few things installed onto the machine. Ventrillo and Steam are really the only things running, aside from CoreTemp and my Antivirus.

As far as I can tell, all of my drivers are up to date.

Is there a way that I can trouble-shoot this by running high-load testing programs?

Any help would be appreciated! If I have been unclear on anything, feel free to ask and I will reply promptly!

Thanks in advance,
Derek
