Can't access OpenCL for AMD Radeon R9 270 I'm running Blender 2.79 on Windows 10 Home Edition 

Specs: 


Processor: i7-4790 CPU @ 3.60GHz 
8,00 GB RAM
AMD Radeon R9 270 (latest drivers)
Intel HD Graphics 4600 (latest drivers)
OPEN CL Version 23.20.15015.1002


According to the BlenderWiki Page, my graphics card should be supported for rendering in Cycles, but OPEN CL doesn't show in user preferences, I'm not a pro with PCs, I try to do things on my own a lot, but this issue is above my head, I can't figure out how to render with GPU...
I think you need to go into user preferences>system> and in the bottom left corner there is Cycles Compute device. Turn this to open CL. Then back to main interface go to render > device and you will see a drop down says cpu. Use drop down and it will give you the option of gpu. Hope this helps!
