Can't change render device

Hello, I’m am here to account a problem I have noticed multiple times. When I try to change my render device “CPU to GPU”, the menu is not there. I have three versions of blender on my computer and in only one of them, which is the oldest version of them, does have an option for changing device. I was hoping someone could help me with that. Thanks.

Hi, hard to do without any informations about your system.
I guess you have an old GPU., mib


Sorry about that.

CPU: AMD FX 8120 8-Core Black Edition
GPU: EVGA GeForce GTX 650
OS: Windows 7 Home Premium 64
Memory: 1TB

I don’t have the problem if I use Blender 2.71
