OK, it appears you've isolated the problem to the chip… suggest you return it for a replacement. There should be nothing in a program that affects a chip… there is an old saying in computer circles that goes something like this, "Software can't hurt hardware". Meaning, nothing you can type in will permanently damage the computer. Think of RAM as an empty bottle, and programs and data as the stuff you fill the bottle with… when you add an 8K chip, you're just using a larger bottle to hold your stuff.
