50-100% CPU usage

The computer I am currently on is running very slowly. I am running Windows XP, but when the system booted and the Wallpaper was displayed, the icons and their names were now bordered in black, which is the color of my background (as it used to look in Win9x). I checked the task manager and found the System Image name was suddenly having bursts up to 100% of CPU useage. I downloaded and used ProcessExplorer to check the particular culprit, and found it was partport.sys+0xe468.

Does anyone know how to fix this, or am I going to need to buy a new Hard Drive for this computer?

Is it partport.sys, or parport.sys?

Search your computer for parport.sys. Normally, it should be located at C:\Windows\System32\drivers
If the file has different location, it's most likely a sign of an infection.
BTW, parport.sys is Parallel Port Driver.

Do you have any errors in Device Manager?
Is your printer connected to parallel port?
What happens, if you shut down that service?

I checked there first. No errors in Device Manager. My printer is connected to the parallel port. Where in the Device Manager would I find the parallel port controller, and what would it be called?

edit: I disabled the ecp printer port (lpt1) and the system cpu usage ended. However, my desktop still has the icons that appear as they did in Win9x: the background shown under the icon text boxes and slightly showing around some of the icons themselves.

Open System Properties in Control Panel, choose the Advanced tab, and click Settings in the Performance section. Turn on the Use drop shadows for icon labels on the desktop option, and click Ok.

It was already selected. I unchecked and rechecked it (clicking apply each time) but the icons and their names remain the same.

Right-click on the desktop, next click "Arrange Icons by..", and then deselect "Lock Web Items on Desktop".

Is it custom wallpaper?
If so, did you try to switch to some native Windows background?

It's not custom. I switched to a native background but it still comes out as seen above.
