Your computer CANNOT run as fast as it is capable of unless you load the main chipset drivers for the mboard after Setup has finished.
XP doesn't have the drivers built in for most things that first came out after XP was first released, circa 2001, and it doesn't have some of the drivers built in for things made before that.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
Sometimes brand name web sites don't list the IAA in the Drivers list when it should be listed.
If your computer has one of the earlier Intel 8xx main chipsets, check the Intel web site for downloads for the chipset to see whether it lists the IAA - Intel Application Accelerator.
If that's listed, you MUST download it and install it in order for your main chipset to run the drives as fast as it can.
If you HAVE installed the main chipset drivers, and the IAA if that applies, if the computer is still running slower than you remember, then try setting the mboard's bios Setup to defaults, or better still optimized defaults,save settings.You may have set some setting incorrectly and that's slowing down your computer.
If that doesn't help, there's nothing you can do that will significantly speed up your computer, with the same ram and cpu.
Although, your system will probably run a bit better if you install max 3gb rather than 4gb of ram

An example of 3gb working better than 4gb in a 32 bit operating system.
See Response 6:
Your computer should be running as fast as it is capable of when you have performed a fresh install of Windows and have loaded the min chipset drivers, and the IAA if that applies, or when a fresh install of it's original brand name supplied software installation has been installed.
An original brand name supplied software installation.already has the main chipset drivers and other drivers your system needs built into it, for the devices it originally came with
A Windows CD does not.
In most cases I've seen, when a Dell computer that had XP installed on it, if it originally came with Recovery disks, the first one is an XP Re-installation CD. I've examined several of those CDs - that has data contents that are identical to that of a regular Microsoft OEM CD, except that some of the *.OEM files have been modified so that the CD cannot be used to install Windows except on your Dell model that you got it with. There are no drivers on it other than the ones included on a regular Microsoft XP CD.
