It doesn't mine because it doesn't see any opencl hardware, of course. This means that you have to install the drivers or choose another miner. Open guiminer, clic file->new miner->ufasoft CPU miner and then set it. It should work. Note that cpu mining is totally useless. GPU mining is no more profitable now too, due to ASIC.
