I am afraid POST is kernel independent feature. Power-On-Self-Test
runs immediately after power applied and, if all went well, invokes
bootstrapping code.
Verbosity of POST is mainly configured into BIOS. Make sure you set up
maximum verbosity level.

To get information about what cause your system not responding it is
better to look up kernel messages. You provide poor information to
make any conclusion or even guessing. Sorry.

When you box is friezed try to invoke "magic keys"
(http://en.wikipedia.org/wiki/Magic_SysRq_key) to collect some
information.

P.S.
Sorry for my English
