problems with clean install of XP Professional

I recently purchased a Dell Dimension E520 desktop. It came loaded from the factory with Spanish language XP Professional. I am trying to do a clean download of XP Professional English version. I get the blue screen with the following msg: STOP:0x0000007B (0xF7A8A524,0XC0000034,0x00000000,0x00000000). 

 I have run chkdsk and found no errors.  I believe this has something to do with RAID/SATA thing.  I turned it off and was then able to install the new XP on  "I" drive.  I thought that would be better than nothing but was wrong, I ended up with memory problems. 

When I booted I could load the English version, if I tried the Spanish version I would then get the blue screen.  When I turned the RAID back on I could load the Spanish but not the English.

I changed the computer to boot from disk, and rebooted with the new XP English disk.  I tried to delete the old XP from C drive but received the following msg: "Setup is unable to perform the requested operation on the selected partition.  This partition contains temporary setup files that are required to complete this installation."  I was able to delete the XP English version from "I".

Now when I boot I have three options,
#1 The English version now gives the msg "Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk.."
#2 is the Spanish version which downloads fine
#3 is another start of an installation that I did not complete but can't get rid of

My goal is to have only the English version installed, and only the one option when I turn my computer on!  Help please.
