Nvidia GTX 660ti has flickering in the footage when a 2 minute video is rendered, but rendered 10-17 second sample clips are unaffected.

Flicker is not in original footage but seems to be added in render and pre-render. It appears in longer renders (see examples below).

System:
EVGA GeForce GTX 660Ti
2.8 GHz, AMD Phenom II X5 1055T
16 BG RAM
2 x 7200 HDs
Drive 1: Programs, source footage, media cache
Drive 2: Renders

Examples:
Non-flicker (10s) - https://www.youtube.com/watch?v=qSfl74jFgrA
Flicker (1m41s) - https://www.youtube.com/watch?v=2-jpaB04e1Y

Export Settings:
Output:1280x720 (1.0), 23.976 fps, Progressive, VBR, 2 pass, Target 30.00 Mbps, Max 25.00 Mbps, AAC, 320 kbps, 48 kHz, Stereo
Note: bitrate setting is sourced from the HQ render settings suggested by https://support.google.com/youtube/answer/1722171
Source: 1920x1080 (1.0), 23.976 fps, Progressive, 48000 Hz, Stereo

Relevant Project details:
There are a few dynamically linked After Effects files in the timeline, but through troubleshooting, those have been rendered as AVI and brought into the project, cancelling issues with the Dynamic link
Instead of applying settings on individual edits, an adjustment layer is used above the main footage for quick color correction (used: Sharpness @ 15 // Brightness and Contrast w/ Brightness @ 0 & Contrast @ 6)

Steps already taken:
Verified GPU drivers were updated
Media Cache has been cleared
'Unspecified Error' was received on a few of the dynamically linked AE files, so they were deleted and recreated
Solution Workflow:
Roll back driver
Render test footage
If clear, rendered longer clip
If unclear, rolled drivers back to previous version
Rendered all linked AE files as AVI and imported into timeline
Instead of using adjustment layer for quick-color correction, main footage was nested, and B&C/Sharpness effects were applied to nested footage
Thinking it may be previous driver installs, all residual drivers were removed for fresh GPU driver install


I'm at my wit's end trying to figure out where I'm going wrong with the setup, render process or what—if anything—needs to be replaced.

Any ideas?
