I hope that's a typo, and you meant gcc 2.7.2.1, which is the current
version of gcc being used by DJGPP v2.01.  If you really are using
2.4.1, you'd better upgrade.

getkey() waits for you to press a key, and then returns the value as an
integer.  I don't understand what you mean by "stop your pc;" have you
tried pressing a key?  Are you calling getkey() from an illegal context,
such as after installing a keyboard interrupt handler?  Are you
including the proper header files?  Otherwise, there's no reason for
this to happen.  If it does lock, can you break out with Ctrl-C or
Ctrl-Break?  Does Ctrl-Alt-Del work?  If you're running in Windows 95 or
Windows 3.1 have you tried running in DOS, or vice versa?

Please cut your code down to the smallest compilable program that causes
your computer to lock up, and post it so we can try to debug it.  Please
also tell us what operating system you are using.
