Instalation Centos 7.0 in HP Proliant DL380 without sucess

Hi,

I´m new with CentOS and I want to install it in a Server. I have downloaded the ISO image and save it as an installation DVD, but every time I try to install it, after I select on the first menu "Install CentOS 7" or "Test this media & install CentOS 7"  I have a black screen and DVD stops reading.

I tried install on two different servers:

1st HP Proliant DL380

       Intel Xeon CPU 2,8 GHz Dual processor

       System Type 32 Bits Operating System

       Memory 4 Gb

2nd HP Proliant DL380

        Intel Xeon CPU 2,8 GHz Dual processor

        System Type 32 Bits Operating System

        Memory 6 Gb

I´d really appreciate your help.

Best regards,

Fernando
