I had the similar problems:
It turns out you must have a bad RAM module. If you have 2 RAM modules in my system. pull one of the modules out and everything must be installed perfectly.
Else my second solution should surely work -
Please try the following.
Changing the DMA access within Windows XP
Here it is ->
Right click "My Computer"
Click on the "Hardware" tab in System properties
Click Device Manager
You should see a section for IDE ATA/ATAPI Controlers.
[Here is where your DVD Roms IDE Connection and also the source of the problem. You will be able to change the data mode by right clicking on the correct IDE channel and selecting properties. Find out if your DVD ROM is connected to the Primary or Secondary IDE Channel. Secondary is most common.]
Right click on your IDE Channel and click properties
Click the "Advanced Settings" tab
Your DVD-ROM will be either device 0 or 1
Change the "Transfer Mode" to "PIO Only"
Click Ok and Close everything. I would reccomend a restart but some may not need one.
INSTALL from the DVD.
Follow the same steps to switch the transfer mode back to its original setting
try cleaning the CD to remove any dirt
