BFGminer running on GPU on Windows 7 I can't get the BFGminer to work on my Windows 7 machine. I've followed the instructions on https://www.btcguild.com/index.php?page=support. But when ever I run bfgminer.exe I get the following message at the top:

Waiting for devices; press 'M+' to add, or 'Q' to quit

I want to use my GPU, as I don't have any FPGA or ASIC devices yet. Can anyone help out?
You can try to "auto-manually" add your GPUs to bfgminer by pressing M then + and then typing auto, or you can use the -S opencl:auto option when launching bfgminer.

NOTE: Not all graphics cards are compatible; various software is required (e.g., AMD APP sdk); it is not recommended to use GPUs for bitcoin mining with bfgminer. 

According to README.GPU, the official documentation for bfgminer on github:


  By default, BFGMiner will NOT mine on any GPUs unless in scrypt mode. If you
  wish to use your GPU to mine SHA256d (generally not a good idea), you can
  explicitly enable it with the -S opencl:auto option.


To start scrypt mining with bfgminer and GPUs, use the --scrypt and -S opencl:auto options, but keep in mind that there are several other parameters to consider. See README.scrypt for additional details about scrypt mining configuration and optimization with GPUs.
