shutdown

My server running is Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux.

About once a day, sometimes once every two days is shut down - It isn't really shut down, it seems like its sleeping - Power button is blinking, but I cannot boot it by clicking on power or reset button, I must pull electricity out and plug it back in, then I can boot it.

What could be the cause of this? How can I fix this?
