New build issue

Hi
ive recently built a new pc, but seems to be a slight problem. made a video so itll be easier for u to hear and see the issue.


The problem occers at random times, not necessarily at high usage. The sound and video seem to stutter every few seconds. parts are listed below. if u need any more info let me know. thanks guys

i5 2500k
Asus Geforce GTX460 1024mb
Asus P8P67 LE Intel P67 Socket 1155
G Skill RipJawsX 4gb (2x2gb) DDR3 PC3-12800C9
Antec TruePower New Modular 550W PSU
WD Cavier Blue 500GB SATA 6GBS 16MB cache HD

other info is kinda irrelevant but will post if needed. hope u guys can help

and sorry about the beginning part of video, the issue is best heard after half way mark, might have to turn up ur volume too. thanks again

Could be excessive I/O, are you running the videos and doing all that off a single hard drive?

Hi sorry didnt have time to respond. Work too much lol. But yeah run everything off one hard drive. Tried swapping ram slots but still happening. thanks for the reply.
