Help! Video/audio stutter

post #1 of 5
Thread Starter 
Recently built a new computer and I've been getting stuttering issues. Thought it was my graphics card, but it's not. The video as well as audio will stutter both in-game and while using desktop. Help will be greatly appreciated. This is my first build, and it's gone awry.

Specs:
NZXT PHANTOM 410 CASE
MSI GD65 Z77 Motherboard
120GB SSD Corsair Force GT
1TB HDD CAVIAR GREEN
DVD+-RW 16x
Windows 7 Ult 64-bit
MSI TWIN FROZR 3 7950 3GD5
ANTEC 750W PSU Model: EA-750 GREEN
i5 3570k
v6gt cpu cooler
CORSAIR VENGEANCE LOW PROFILE 2X4GB 1600

I would assume it's the slow HDD causing issues, depending on how you have your drives configured.

Most likely your SSD,

Check out this thread there's some solutions: Problems with Force GT Drives -Freezes and Hangs

My Vertex SSD had stuttering problems because I installed windows with BIOS set to IDE mode. After reinstall in AHCI mode problems went away.

came back...


Anyone know of the reasoning? It went away for a while, but I heard it again while watching youtube (once).


Here's results from latencymon and dpc latency checker:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:17:08 (h:mm:ss) on all processors in the system.
