Daily, successive kernel panics - how to identify root issue?

A few weeks ago, my computer suffered from some water damage. I sent it to an Apple repair center where most of it was replaced, including the logic board, speakers, discrete GPU, and I/O board.

After using it for 2 days without issues, I installed OS X 10.9.4. Since then, I have had multiple, successive kernel panics every day. Strangely, these are not easy to reproduce; I can go 12 hours or more without having a problem. Then, in the middle of scrolling in Safari or opening an application like Preview, the graphics will glitch out and the system will crash. After one crash, further crashes can happen within seconds or minutes of a reboot.

Things I've tried with no luck:

• NVRAM reset
• SMC reset
• Apple Hardware Diagnostic
• verified the SSD with disk utility + repaired filesystem permissions from recovery mode
• Rember memory test
• memtest86 from a USB stick
• tried to induce crashes by stress-testing the discrete GPU
• unplug all peripherals (I have a mouse and headphones with an integrated microphone) - still get panics with them disconnected

Initially, I suspected that my Razer mouse drivers were to blame, but I've still been getting panics since removing all of my 3rd-party kernel extensions.

You can see all of my panics here: https://drive.google.com/folderview?id=0B6JO6Q_WYjb2TURkU1N5ZWprbTQ&usp=sharing

Lots of them relate to IOkit

This is the strangest panic:
