I had a similar experience many years ago. The very first test I did with every build was press both hands on a bunch of keys. It almost always locked the system up completely. So I'd reject it. The lead programmer (who as an idiot) kept saying, "don't do that." My response was, "that's a cat jumping on the keyboard, or a tired person accidentally leaning on the keyboard. It's something that will happen. And when it does, it locks the system so tight you have to do a hard reboot." BTW, this was back in MSDOS days.
One day he told me my job as QA wasn't to QA the program (like I said, he was an idiot). So I said, fine, and quit on the spot. I don't do QA now. I hated it. Now I'm a system admin.
