Electrical JOLTS!!!! HELP!!!

Hi there , I see you guys are very expert on thechincal stuff , so if you could please help me out !!!
I own an MSI 12.1" centrino solo , 1gb ram 100hd intel wireless and intel videocard .
One day suddenly ,while i was working with the transformer plugged in, i touched the usb ports and I actually took a very big electrical shock, so i've tried to touch near the wireless exit another shock , on the headphones out , another shock , mic in the same , almost an all the parts probably near metal things , so except the keyboard and mousepad so im now writing avoiding even the minimal contact with other parts.
When i plugged it off from the current , runing only with battery, it runs great of course.
So what the problem could be ?
What should I start to check , before opening the laptop ? check the transformer ? cables ? plug in the wall ? or could it be a problem related inside the laptop , maybe due to overheating let's say it burn some parts and some electrical wires are now touching some metal parts wich are conductive in the whole laptop.??
pleaase help me out guys !!!!!

 

since it's a yonah, you must have recieved the notebook recently. i'd definately have whoever you bought it from fix it.

 

the problem im in maldives right now , anyway the warranty is already expired, i bought it 2 years ago.

 

Sounds like a problem with the transformer to me. I'm no expert, but maybe its supplying too high a current therefore its transferred to uh, you, in the form of electric shocks?

 

Must have been because it was friday the 13th. I wouldnt worry.
