Extraneous protocol slowing PC down?

I just uninstalled a wireless network adapter on my XP PC, and swapped from an LCD monitor to an old CRT monitor. Now, my PC runs much slower.

Under Properties for my motherboard's network adapter, I see the following in the "This connection uses the following items" listbox:
 - Clients for Microsoft Networks
 - File and Printer Sharing..
 - QoS Packet Scheduler
 - AEGIS Protocol (IEEE 802.1x) v3.4.3.0
 - Internet Protocol (TCP/IP)

I am not familiar with:
 - QoS Packet Scheduler
 - AEGIS Protocol (IEEE 802.1x) v3.4.3.0

Could the inclusion of these be slowing down my PC because the wireless adapter is not longer installed?
What else, (related to the removal of the wireless network adapter, or swapping from an LCD monitor to an old CRT monitor), could slow my PC down?

if the computer is now on a slower network cometimes windows updates slows the machine down - try turning windows updates off or to manual,
the protocols are normal - the monitor shouldnt be related at all.
clean up your temp files and do a defrag.

isn't 802.1 a wireless protocol? If so, any problem removing it since I no longer have wireless adapter on this PC?
