Whenever I open a word document in my windows 8.1 system, the PC becomes unresponsive. The hard disk keeps working but the system does not respond to any single action. I have to always switch it off from the power button. It is only happening when I open an office document. Any other program runs completely fine for as long as needed.

How can I report this huge problem to Microsoft. My laptop will get damaged from the situation and Microsoft will never take responsibility????
