You need to install motherboard (main) chipset drivers, and other drivers.
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.
Load the main chipset drivers first.

"If your XP CD does not have SP3 updates included, the best time to load them is right after you have installed Windows from scratch...."
Getting your system back to the way you had it before is a lot of work if you re-install Windows from scratch without saving the data on the C drive you do not want to lose before you do that.
You probably didn't need to re-install Windows.
By the gist of your description, you probably had this, and you probably could have gotten rid of it by running Malwarebytes.
See Response 4 - probable "Rogue" anti-malware crap was installed - wireless networking disabled - try using Malwarebytes.
