And yes unfortunately none of the wiring in my house is grounded (they have grounded outlets but they don't have ground wires running to them at least according to my surge protectors which show the ground light being unlit which means they are not grounded) they have a "ground wire" running to the electrical panel (which is actually just them running a "ground wire" to one of the old lightning rod "ground stakes" next to the house, but other than that there really isn't any ground wires going to any of the outlets in the house.)

If the electrical service in your house is not properly grounded (or, worse, not grounded at all), it may well be in violation of the National Electrical Code. I am by no means certain, but I think the NEC does state that all houses built after a certain year must have 3-wire electrical service.
Just because you have 3-wire outlets in your house does not necessarily mean the AC wiring is grounded; in fact, from what you said in your post, there is no proper ground anywhere, except that "ground wire" you mention which runs to a ground stake near the house. This sounds to me like a very poor excuse for a "real" ground connection. In addition to this very likely being a violation of the National Electrical Code, it could very well be a fire hazard if anything shorts out anywhere in the home's electrical system. I would have this checked by an electrician and corrected as soon as possible. This could also explain why your housemate's computer is radiating noise everywhere through your home's electrical system, although if the power supply is that noisy, it is not normal and should be examined as well.
