machine is freezing all the time, cannot do anything

Dear all,

As I send this message, I run the risk of it not
getting to where it should.  The machine is constantly
freezing.  I cannot do anything with it anymore :(

What should I do to troubleshoot it?

I tried to install the update, but the machine crashed
