If you check earlier i advised him to check if its HDD problem or Windows problem by formating and installing windows on his old HDD.
He said he couldnt so im assuming that the SSD is 100%.
Now since he said he wanted to keep the windows inside his old HDD and with what you said and also taking in consideration you might be right.
The only option available i can see to exclude either faulty ssd or windows problem is creating a new partition inside the old HDD and dual booting Windows 7.
Or if the OP doesnt wanna do these steps and the SSD is brand new just go to the store and replace it.
