BTC recovery of wallet.dat – Bitcoin Stack Exchange

I started mining in March 2009, I remember my registration. is there a way to recover my CTB from the registration process? I know you need the wallet.dat and the password or the key to access the BTC, but is there a way to get my BTC? I am desperate, knowing that I have money in the ether, but I still have none killing me. I vaguely remember that when I registered they had just added a registration process linking my information to the pieces generated in 03/2009. I know that there are sleeping address lists, can they be used to recover my BTC? Please help
