strange behavior of bash

[faif cn]

Hello all,
 
 I deleted some values in Windows Local Environment variable "PATH".
My original "HOME" is c:/home/myname/. And then:
 
 In DOS promote:
 
 If I type "bash" in any other directories, the bash promote can be
shown successfully and I can use bash environment.
 
 If I type "bash" in my home directory, it just hangs for seconds and
back to dos promote and nothing happened. Alternatively "bash --login"
has same behavior.
 
 Anyone can hlep me  with this, thank you very much.
 
 Leo
