This computer came with Microsoft Windows Vista Home Premium preinstalled. To install windows XP on this machine, first we need to change the boot drive order. Set the boot drive order such that the machine reads CD/DVD drive before reading the hard disk drive. Inserted Windows XP CD in the CD/DVD drive and restarted the computer. Formatted the C: drive and removed Windows Vista Home Premium and selected the option to install Windows XP on the C: drive. After the installation of Windows XP was complete, it was time to istall the drivers. It was actually very hard to find XP drivers for all the installed hardware on this machine (Presario SR5130NX). The three important drivers that I needed for this machine were:

Driver for GeForce 6150SE nForce 430 (http://www.nvidia.com/object/winxp_175.19_whql.html)
Realtek driver (http://www.realtek.com.tw/Downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=23&Level=4&Conn=3&DownTypeID=3&GetDown=false)
USB drivers

It is important to have Windows XP Service Pack 2 installed on your machine before you can install Realtek Audio and GeForce 6150 nForce 430 drivers. Realtek would refuse to install and GeForce driver wouldn't make any difference if Windows XP Service Pack 2 isn't installed. So it is important to update your XP to XP Service Pack 2 if your XP isn't already XP SP2.
The final step is to update your USB drivers. Use windows automatic Search and Install drivers utility to update USB drivers. Restart your computer once done with all of the steps and that is all you need to do to make this Presario SR5130NX work with Windows XP Service Pack 2.
