windows 7 - Why does my screen flicker and my laptop crash?

I have a Dell laptop with Windows 7 on it. Every so often the screen goes exactly like the one in this picture (Why does my screen flicker only in Windows 7?) and freezes. Nothing works and I need to switch off the laptop manually. I've run all sorts of hardware tests with help from the Dell hardware support team. They found nothing and say it's a software problem.


This usually happens once a week but on a very hot day recently it happened five times within 8 hours. So I'm wondering if it could be overheating. The Windows refresh rate is set to 60 and the screen resolution is set to 1366x768. If it is overheating, what can I do to solve the problem?


And what kind of software problem could it be? And how to fix it?
