Sorry to post this PM I received, but I'd hate being responsible for any damage.
From what I understand, you just need to copy your wallet.dat file (from old computer) to a secure location, before you reinstall QT on the new computer.
Then copy back your wallet.dat to the new computer, and you should be fine, once the blockchain has finished updating (which can take up to a a long time (weeks), depending on your bandwitdth).

thanks its great now just want to ask where is wallet.dat and how I can copy this and I have one more problem I done encrypt my wallet and have password how can I unlock this

Wallet path depends (mostly) on OS.
What OS do you use?

OS mean I am checking all this and then tell you

OS = Operating System, sorry.

Linux? Windows 95? Windows server 2008R2? Jelly Bean?

Windows XP Professional Version 2002

Then open a windows explorer (win+e if not sure, hold both keys together), then browse to
C:\Documents and Settings\YourUserName\Application data\Bitcoin

Replace your YourUserName with your actual user name, and you should see a wallet.dat file.
If so, copy this file it to a usb stick, for example.

as you explain I open and have 4 folder and 1 .DAT file now I have saved all these in USB

Search for for any other wallet.dat file (win+f => walllet.dat) on your old computer, before, and backup each of those.
Then let your new computer download the blockchain. This can take a lot of time, don't lose patience.
Quit the QT client (on new computer), and copy the wallet.dat backup you're the most confident with over the empty one created on you new computer. (If same OS and same user, same location).

ok thanks I done all this now in next few days as I have new computer and do this then if need then send you message from this thread thanks a lot great help  :)

You're most welcome, bump this thread if anything goes wrong. Good luck!

hello sir hope you are good and enjoying really good and informative thing I done last night now want some more your help I want to do some mining is this ok these days and which is better I have 3 options  Bitcoin, Litecoin, and XPM please give your comments about this

Spreading your mining effort across all 3 does not seem bad to me.
But keep in mind this is my opinion, and it's probably worthless.

mean mining is not profitable right now I talk to my few friends also most saying its not good idea so now you also saying now I am dropping this one I was asking just because of this have no job for long time and now just doing a signature job and some captcha work need some good work

hello sir just want to remember you now I have new computer and downloading bitcoin qt and its already reach to 13 week behind as i complete this I need your help for adding my old address and recovering my coins just tell me could you available on monday

Good to hear you got that almost sorted!
What is your new computer OS?

I love to use WINDOWS XP so again done this but this time have hard disk some big

edit  I am doing also CAPTCHA work so just because of this I need this WINDOWS XP some software's works on XP better  

Then once you're done with getting the blockchain, shut QT down, replace the empty wallet it created in your
folder by the one from your usb stick.

I would also make another copy the wallet.dat somewhere else on your harddrive (I don't really trust usb sticks with such "important" data)

After that, create/edit the shortcut you're using to launch QT, and add " -rescan" in the end of the "Target" input box.

Should look like:
where ... is the location of your bitcoin-qt client.

Your balance should be ok, then.
If not, don't panic, QT is sometimes a bit dodgy when it comes to computing balances, we'll find another way.

Hello Sir if you are in North America or South then good day I was waiting for you just its completed all downloading and ready for this now what is my first step for adding my old address please some describe if you can do on team viewer than I can send you id and password please solve this and thanks for your time

I'm sorry, but I'd rather not connect to your computer.
Is anything unclear in the following sequence:
- Shutdown Bitcoin-QT
- If your current wallet was not empty, copy it to a safe location
- Replace your current wallet by the one your extracted from your old computer (make sure you don't delete this "old" wallet until you successfully moved the coins out of it)
- Restart QT with a "-rescan" switch

some is understandable for me and now trying to do as you are saying hope its works for me my current wallet is empty and now trying to replace this one

edit: is there any video link available for this work  I done some and old keys shift in userdata and now going to try rescan switch

I am sorry for disturbing you again and again now I have puts files in user-data and now just want to know how I do this rescan if you can send screen shot its better because just want to ask how I do this rescan now going but I wait for your reply

Shutdown bitcoin-qt
Locate your bitcoin-qt.exe (use the windows search feature if not sure where to look).
right-click on it, then "Create a shortcut"
right click on newly created shortcut => Properties
In the "Target" textbox, you'll see the full path of you bitcoin-qt.exe
Just add " -rescan" in the end of this full path
(should look like "...\bitcoin-qt.exe -rescan" where "..." is the location of your bitcoin-qt.exe)
click on Ok.
Relaunch QT using the newly created shortcut.

G'luck!

its very late here but still happy to work with you so as you explain I do this but this message is coming  The name C\Program Files\Bitcoin\bitcoin-qt.exe-rescan specified in the Target box is not valid. Make sure the path and file name are correct.

You just need a space between bitcoin-qt.exe and -rescan, like that:
...\bitcoin-qt.exe -rescan

"C:\Program Files\Bitcoin\bitcoin-qt.exe -rescan"   this but again same message coming

Ok, let's try another way.
- Hold windows+R
- in the box that pops up, enter
- hit ok
When the black window pops up, enter:
hit enter
hit enter
hit enter
hit enter

This should launch the client with the rescan switch. :D

its done and now again 13 hours behind and out of sync but no coins in this how I add old account now I hope we do this  :D

When you're done with catching up with the blockchain, if your balance is still incorrect, this will require more work, I guess.
At least you're learning, in the meantime. ;D

good day hope you are good and enjoying its almost more then 14 hours its still on 13 hours behind nothing happening what I do now

what is time on site when we can do this easily please tell now its very late here I am waiting for you but cannot sit but want to work with you  :)

Are you still "13 days back" with the blockchain?
And don't worry, if the backup wallet includes your private keys, you did not lose anything.  :)
