Widely varying FPS and microstuttering

[flippsided]

Hi all,

I am new to computing and have recently stepped up from a gaming laptop (Alienware) to a shop built custom PC. From my limited knowledge, the components were decent to high spec and I expected better performance.
When gaming, the FPS ranges from 9 to 70 and is jumping around erratically. Microstuttering occurs where I see pause in frames and hear a ripping type sound. I have tried disabling the Nvidia HD sound, the SoundBlaster sound, enabling V-Sync and limiting settings from ultra down to low etc. Nothing seems to work,

System is as follows:
Kingston HyperX 3K 120GB 2.5" SATA III SSD SH103S3/120G
WD WD20EFRX 2TB Red 3.5” IntelliPower SATA3 NAS Hard Drive
Microsoft Windows 7 Home Premium SP1 OEM 64-Bit
Corsair CX-600M 600W 80 Plus Bronze Modular Power Supply
Corsair Graphite 230T Mid Tower with Window - Black/Red LED Fans
Kingston HyperX FURY 8GB (2x 4GB) DDR3 1600MHz Memory Black HX316C10FBK2/8
MSI Z97 Gaming 3 Intel LGA 1150 ATX Motherboard
Intel Core i5 4690 Quad Core LGA 1150 3.5GHz CPU Processor
Samsung SH-224DB 24x Internal SATA Retail DVD Burner Drive
MSI GeForce GTX 970 Gaming 4GB Video Card
BenQ XL2411Z (144Hz) 24" 1ms HDMI Full HD Low Blue Light LED Gaming Monitor

Any advice, guidance or experience from similar problems would be greatly appreciated.

Download HW Monitor and SpeedFan, make sure all of your temps are not too high.
Possibly a throttling issue?
