The 3000 originally shipped with XP as the operating system, so no problem - actually, Win2000 isn't even listed as a supported operating system.  Was it shipped with 2000, or was 2000 installed later?  If later, then your original OEM license is for XP and you may be able to get replacement disks if you don't have them (see step 3 for the form).  If it came with 2000, though, you'll need to buy a copy of XP:

Good idea to get the drivers you need downloaded ahead of time - it's much easier to identify your hardware now than it is after installing XP.  Dell's driver installation order here:

My system came with 2000 installed.  But I also have a operating system disk of Windows 2000.  I'll kook up the OEM.

 

My system also came with Office for Windows 2000.  Can this be used with XP?

 

Thank you for your wonderful assistance.

Interesting.  There should be a sticker somewhere on the tower with the original operating system and product key.  Or, if you don't have the original invoice, see if you can get it here - it will list what operating system it came with.

Office 2000 works fine on XP.    My copy was originally installed on Win98.
