GEU
The GEU is actually the Gerbal Energy Unit found in most computers dating back to the early 90's. You can check to see if this is working by picking up your modem and rattling it. If you hear squeals, it's working. If'n you hear clanking bones, time to clean out the filter...
Wow, you're computer's movin' slow. Yo, it's time you checked your GEU, holmes.
