1) please try to use english to describe your problem you were able to use English to request help so you should be able to describe your problems in English too.
2) Do not put your email address in your post its a very easy way of being spammed.
3) ok so i can understand your question as i kinda know the language!!!
So to put into English for everyone else:
My computer just hung randomly while using it, even after restarting i get no display but the computer seems to start up (i assume he means lights and fans run) and the keyboard lights start to flicker.
sounds like you may have issues with either your power supply or your graphics card,
