Hopefully you have a functioning ELCB at the main incomer which is at the current legislative requirements (UK) of 30mA, so if things do get worse you have some protection.
Thank elephant for decent safety legislation - I know we all knock 'elf & safety, but having lived in a place where the [rare] actual standards are flouted I'm glad we have them & they are adhered to. Over in the middle east the "electrician" we had in extended the cable to the portable electric heater - he wired a existing 13a three-core cord to the sort of two-core cable commonly used for doorbells. He didn't even use a junction box - just electrician's tape - double plus good when the cable was run across the floor with children running around. I wired up a proper extension cable - when I found out, and I only noticed it something was wrong because when I trod on the doorbell cable it was warm underfoot... I blame the "it is written" mentality in the Middle East - it took some convincing that just leaving this to chance was not a good idea, especially in a tinder-dry room.
The amount of energy necessary to refute bullshit is an order of magnitude bigger than to produce it.
It is probably stray capacitance that's giving you a small leakage current. However, as others have said, it's a symptom of a potentially serious fault and you need to get a professional to look into and rectify the problem, and the sooner the better.
If indeed there is no main earth connection, but you have appliances with metal cases that are connected to the (floating) earth, then a second fault in one of those appliances could make the cases of all of them live. The consequences of that would not be good.
BarrRobot is right sir.
Many appliances (washmachines, computers, microwave oven...) have Pi filters with small capacitances linked to the metal case that make an voltage leakage on cases when earth (plug) is not realy earthed (grounded) from main power supply. The actual leakage current may be not sufficient to make protection effective (30mA min.)!
You must connect ( if not) an additional earth (ground) fault protection device to the earthed (grounded) connectors.
Any case, the electrical system has to be earthed and that it have to comply with safety standards.
I hope I'm right - I'm a Chartered Electrical Engineer!
I can think of a relatively simple test to establish whether there is indeed a missing earth connection, but the test itself would involve an element of risk. As there is a strong indication that the installation is not compliant with the safety standards, professional help is the only course of action that I'd normally recommend.
If you are familiar with the current regs and have the correct equipment by all means trace the fault and fix it yourself . Failing that , and recognising that because you do not know the cause then it could potentially lead to electrocution ( which tends to be a bit ouchy if your lucky or a bit deathy like if your not) Then I would get someone who does know the regs and does have the equipment . I believe they are called professionals . Just imagine this as the coding VB6 to control an aircraft whilst you are on the aircraft . It might work , there might be no issues , but ? Really ?
Bought a new PC for the parents after my long trusted XP box died finally. All I can say is "Yuck!" a start button that takes you to metro? no start Menu, I get the impression that its all for the Surface / Windows phone and shoe horned on to a desktop. The only thing is the speed at which it boots (probably because there is nothing on it at the moment!). Well that's 20+ years of familiarity down the drain, trying to get Security Essential's to find Bit Defender is in place already took a little while to figure out. Can anybody tell me why you need a touch screen layout on a desktop machine? Vista was a little odd compared to this Elephant!
Mmmm... saw that on Saturday I was looking at it thinking am I creating a backdoor here, will that cause parents to be bombarded with more spam than they were getting already (my Dad had the habit of putting his E-mail on everything, just maybe...)

I don't think Windows 8 really shuts down unless you tell it to specifically, I've seen issues with people being confused by a long uptime (in sysinfo) after starting up, shutdown in Windows 8 is basically a glorified hibernate.
I know your parents will resist the change, as you seem to be doing.
I accepted the change when W8 first came out and learned how to navigate this new landscape. Now I am actually changing my file type preferences to Metro (I know I shouldn't call them that) style apps because I am used to the presentation and old school apps seem so 20th Century. Kind of like when windows apps started to replace DOS apps.
Are you one of the people who prefer DOS apps styling?
Once you lose your pride the rest is easy.
I would agree with you but then we both would be wrong.
