Hello,
     I noticed my hard disk shocks and the casing compartment housing it if touched when I'm putting on nothing on my foot (i.e shoes/slippers ) .
    Can any one tell me how to go round this.
Thanks

Two things:
1) Swap the power supply - your current one may be leaking current to ground.
2) Get your house outlet checked by an electrician - it may have been improperly installed.

By properly installed the ground must be connected.  Most older houses (50 or more years) do not have a ground built into the electrical configuration of the house.  With time the outlets have been changed to 3 pronged outlets.  These outlets have been installed without a ground making many household electrical safty devices useless.  One major example is a surge protector.  Without a ground you might as well just plug just right into the wall.  If this is the case with your house, then I would suggest that you have certain things or outlets rewired to include a ground wire.

I have not posted on this topic because i happen not to have exhausted the options given by callandor above before now. I have verified option 2 long ago and I ascertained that the power outlet is not the problem because i brought another system to check and it gave no shock and thesame applies to all the outlets on the block . but for the optionof changing the power supply unit i have just been able to do that but thesame thing still hapens so what do you suggest i do now. Thanks

just because another system did not shock you, does not mean that your outlet is grounded correctly.

Well I have actually moved from my former hall to a new one entirely and thesame thing still happens. I think i have ruled out the possibility of the outlet being the problem right now, though it may be bad since i never got a technician to check the outlet before i left my former place. Right now i think this shocking thing is internal to the PC bcos i even had to take it  out for a programme and i still felt thesame shock even there too.
A friend of mine said that there is a screw that is making earth contacts with the motherboard and the casing. I have not verified that yet, but what do you think.
Thanks

I could see where that is a possiblity, usually when that happens though, your computer will not work.  

You could also have a problem with your power supply not being grounded correctly.   By this I mean the power supply its self has something wrong with it.

You have to be using a power supply.  It is a componet of your computer.

If you are using a UPS, then I would assume that it would be one of the two not being grounded.  Which means that one of them is not functioning correctly

You mean the fault may be either my UPS or the System Power supply unit right ?
