Edit the whole first post because too much information is missing or doesn't make sense and start from the beginning.
I bought 165000 Bitcoin in 2010. I invested it in the mtgox.
Did you buy bitcoin somewhere else and sent those coins to Mt.Gox? Or was the purchase completed over the exchange and the coins never left Mt.Gox? What did you invest in Mt.Gox?
My computer crashed in 2013.
That means nothing if the coins were at an exchange.
I was not worried as I had my private keys in a safe but my written paper notebook ruined and cannot read my private keys.
Private keys of what? Were your coins ever withdrawn from Mt.Gox, and if so, where did you send them?
I have found my main passwords.
Passwords of what?
Please help me out to import my Bitcoin address into my new computer.
Importing an address won't allow you to spend the coins from it. The transaction needs to be signed, and it gets signed with the private key.
Edit: You posted while I was creating this post.
I saved my private keys in a diary but that diary got damaged.
Is the damage to the notebook beyond recovery? Can you read none/some/most of the characters of the private key?
I have my wallets password of my computer. But my broken computer was in my family house and mum puts in the computer in dustbin. I hand no idea that I could have restore the data from the hard drive. I now live in abroad. I don't know how to import my wallet in my new computer.
Your mother threw the computer away and you no longer have it. Since there is no computer, there is no wallet or wallet file either. You probably have the decryption password to the wallet file, but without the file it's useless. It would be like if you had a key to a house that got completely destroyed in a fire and doesn't exist anymore. You can't do much with it.
Also I need help to see if I can get some Bitcoin back from the mtgox.
I am afraid the coins in your private wallet are lost and are beyond recovery. You might have more luck with the BTC that were left in your Mt.Gox account when the exchange got rekt. But you need to prove the account belongs to you, and I am not sure if you can do that.
