I guess you do not have access to your old Intel hard drive? If that is the case you can't get your coins back.
Otherwise you can still copy the wallet.dat from the old hard drive.
You need the original file "wallet.dat". Do you have it on the old HDD (I assume you got a new one).
Unfortunately I cleared the SSD before selling it on :/ I've had a look on my mining rig and it has a lot of files in the APPDATA Bitcoin folder, but it doesn't have my wallet. And on slush's pool's website (the pool I used) it shows all the bitcoins that were sent to me. Anything I can do with this info?
