Usually, changing the hard drive wouldnt speed up your laptop but changing the memory will boost the laptop. How much ram is installed in your amilo laptop? Do you multi-task and use high end processing software? Try to uninstall some software and check whether the system is slow or not? You can also try to perform a virus check, so read up some guides made here - http://forums.techarena.in/guides-tutorials/501102.htm

The problem not for speed
The old HDD has change becasue Damge I change it
after afew days The system not working good
I try to instal windows again The Installtion not compelet it's stop during installtion
This is The problem
should I buy new HDD

The systems performance has degraded after changing the new HDD and hence I think it is more of a overheating issue. If the laptop gets overheated, the speed of the laptop will reduce. Hence check if the cooling fan is working properly on the laptop and if possible implement an extra cooling solution like Cooling pads.

Because I receive many laptop siemens It has same problem with same model

When you say that the Windows reinstallation cannot finish installing the OS, then it might be a problem with the OS Cd itself. Have you tried installing from the same OS cd in some other system, was the installation done successfully? Try to get some other OS cd's from your friends or nieghbour and try to install the Operating System again.
