Windows 7: Application specific lock ups.

Application specific lock ups.

I have been trying to diagnose a particular problem where applications freeze for a split 2-3 seconds at random intervals. I really hope that someone might be able to provide some suggestions as I am starting to pull my hair out with this.

For example, I could be running the following programs:
Google Chrome
VLC Movie Player
Skype
Playng TERA Online.

While playing Tera (current active program) and watching a movie on VLC. VLC will freeze for a few seconds (at random) and then continue, while the game I'm playing does not freeze at all.

Another scenario:
Mozilla Firefox
Quicktime Player
MS Office - Excel
While reading a webpage in Firefox (current active program) and listening to music with quicktime, as I scroll through the webpage the browser will freeze and become unresponsive for 2-3 seconds. Meanwhile the music playing in Quicktime has not missed a single beat.

List of attempted fixes:
  • Checked Event Viewer(Applications) for errors, none found.
  • Adjusted Virtual Memory/Paging file from 8162MB to an Initial size of 16324/Max 32648
  • Ran stress test (passmark) To check if I could isolate the freezing during certain tests. (Did not lock up at all after running 5 tests)
  • Used Windows Error checking (CHKDSK) on physical drive to check for errors (none found in Event Viewer)
  • Updated GPU to latest driver version (v301.42)
  • Removed secondary GPU(GeForce 8600 GT), Ran with only Primary GPU(GeForce GTX 560Ti)
  • Used Windows Update to verify latest updates were installed
  • Updated BIOS to latest version as per patch notes: (2012/04/26 - vJ.8) - Improved memory compatibility.
  • Formatted HDD NTFS, re-installed Windows 7 Ultimate x64, updated all drivers for motherboard, GPU and other external devices.
  • Confirmed BIOS settings for CPU were set to Auto due to prior OC'ing
  • Disabled Windows 7 Core Parking, as per information here: Windows 7 & Core Parking .... a *better* way to Turn It OFF ....
  • Swap out both SDRAM modules and replace with new (same model, check below for specs)
  • Swap out CPU with new AMD FX-8120 8-core, after verifying problem remained, installed previous CPU (AMD FX-8150, check below for specs)
  • Removed Primary GPU(GeForce GTX 560Ti) and ran only Secondary GPU(GeForce 8600 GT)
  • Changed BIOS settings for SDRAM (latency/voltages) from AUTO to 9,9,9,27T 1.648v (check spec sheet from CPU-Z below)

The only hardware pieces that have not been swapped out physically is the PSU, MB and HDD(Sata)

I think tonight I will purchase a new hard drive, also contemplating on whether or not to try Windows 8. I will post the results.

I installed Windows 8 and still had this problem, so I replaced my HDD and that seems to have resolved it.

Very strange how the HDD could react in a way that would cause one application to lock up, while everything else was working great. Regardless, I guess I don't fully understand what's going on in the background while Windows is running.
