|Why would you want to go backwards from Windows 7 to XP???|
I have used Windows XP on many machines since 2002 and in general I was satisfied with it (windows 95 was new to me but easy to learn - way back when - windows 98 was a good refinement on it, more secure and generally faster. Windows ME was a disaster. Windows XP was a giant leap forward and a good system though it had many holes that constantly needed plugging (constant updates). Vista - not quite as bad as many would like you to believe - BUT it was half baked - a Rush job - more secure but very annoying for many. NOW Windows 7 arrives! This is what Vista should have been!! It is fast, secure, and on new hardware, easy to install and run. Windows 7 has some quirks that you will get use to and FINALLY fully supports 64bit computing (on programs written to take full advantage of it, blazingly fast). Most programs that ran on XP are running fine on 7, of course I downloaded the latest version of my AntiVirus/AntiMalware program and I would recommend the same for most utilities you use that are not already included in windows7.
IF you are having problems with Windows 7, first look into hardware: You appear to have 448MB RAM according to your spec's but Windows 7 32bit needs 1GIG RAM and runs better on 2 GIG's; 64bit NEEDS 2GIG's RAM and runs better on 3GIG's or more (I built with 4GIG's with Home Premium 64bit) <<To prevent system Mfg's from short-changing people, I would recommend that Windows 7 start with a warning "You have less than the recommended memory installed on your system! It will run anyway, but performance will suffer!" under conditions like yours.>>
IF you need to run work related software that will not run normally under windows7, you should consider Windows 7 Pro and download XP compatibility software from Microsoft. IF you have favorite software or games that will not run, look into newer versions of them, they will probably have other improvements included as well as additional compatibility.
ASSUMING based on your RAM, you are probably running off the motherboard graphics, If you use graphics intensive software or games, consider adding a good video card as well as 4 GIG's of RAM or more.
ALL that said, there may not be drivers available for your newer hardware for XP and it definately will not be on a 2002 version disk of XP. IF you can collect all of your drivers on a floppy disk (if you have one) as your XP disk will not support finding them on a USB source OR you will have to remake your XP disk with the drivers on it (others would have to tell you how to do that). THEN you will have to make sure that your CD/DVD drive is first in boot order to load it. --- NOT worth the trouble for a system that will be obsolete in a few years at best. I doubt that MS will support XP with additional updates for much more than that.
Summary: Try a few UPGRADES first before trying a DOWNGRADE!!!
*** MY OPINION of course***
