Program built using Unity3D Freezing PC - Sporadic - loops

Question

My program that I built using Unity3D sporadically freezes, and this action freezes my computer. I'm unable to pinpoint the root cause. I had placed logs all over my project, but the game failed to freeze.
Has any Unity3D developer experience their apps sporadically freeze in the manner in which I am describing? Does anyone have any ideas or suggestions?
Due to a 30K character limit, the below object has been modified slightly. This is the object I believe contains a flaw, but I am unable to identify this flaw.

Answer 1

I believe I have narrowed the freezing down. Simulated testing results is leading me to believe that my problem is inside the OnGUI() method. I have commented that method out all together, and my app is operating smoothly. I'll figure this out, unless someone beats me to the root cause and solution.

Answer 2

I solved it...
My initial suspicions were correct: the problem did lie within the OnGUI() method. I moved the following source code to the Start() method. It made sense, since I'm only building a transparent background texture once.:
Texture2D texture = new Texture2D(32, 32, TextureFormat.ARGB32, false);
for(int i = 0; i < 32; i++)
{
for(int j = 0; j < 32; j++)
{
texture.SetPixel(i, j, new Color(0.0f, 0.0f, 0.0f, 0.25f));
}
}
texture.Apply();
