The Installation Was Interrupted Before How Can I Deal With A Memory Lockup?

How can I deal with a memory lockup? - the installation was interrupted before

I installed Windows XP on my system twice and followed the advice I received through your website in order to resolve the problem.
I invited third plant, waiting for the option for both partitions and create a new one Delete to complete the installation. However, before reaching this stage was too little memory and could not even work in safe mode, because it was interrupted by the installation.
I had to buy a new computer) (8 years old
But I dare not throw.
I hope that fix the old one to use for my grandchildren.
No advice on what to have done that? Bearing in mind that I have to install more memory and possibly a new hard drive.
Thank you for the board, until I can access all the answers, because I am not a working device.
