why my computer shut down itself every half an hour while I am still using
it? it makes my works all gone.

If it's actually shutting down, this sometimes a sign of overheating or a
problem with the computers power supply. Also, you might want to check
Event Viewer under Administrative Tools and look for any errors that
correspond with this event. Double click the error, the information it
reveals may give a clue as to the source of the issue. Is this a laptop?
If yes, when you use it, are making sure not to block its vents.

Does it do the "shutdown sequence" or it shuts like there was a electric
power failure?

That's very often a hardware problem. not a Windows one. I'd suspect
overheating or a flaky power supply. Sometimes bad RAM, too.

If it acts like a power failure, it's quite possibly the BIOS sensing a cpu over temp and
shutting it down.
One way to tell if that is the issue is that the machine will not respond to the power
switch for a few minutes.

I had it happen on my new machine a couple of times because the heat sink and fan we're
not properly seated.
