I tried ethminer from C++ eth implementation (I know it is in beta, but miner should work, right?)
I first started geth with:
geth --rpc --rpccorsdomain localhost 2>> geth.log
Then I try to launch test CPU mining:
C:\Program Files\Ethereum 0.9.41\Release>ethminer -M -C

Same with GPU mining on embedded Intel 4000:
C:\Program Files\Ethereum 0.9.41\Release>ethminer -M -G

In this case it at least gives reasonable error message, probably my GPU just doesn't have enough memory (no surprise, this is shitty embedded unit).
Ok, try NVidia GPU:

Doesn't work either. What am I doing wrong? I assume GeForce 635M should do something?
Comments
But why CPU mining is not working? I know it's ineffective, but I'd like to try anyway.
-U option is not recognized by my ethminer. Ethminer --help do not list it either.
I assume version on Windows does not support that?

Invest in a gaming PC and mine, or invest in ETH with $$
But with that integrated chipset, you can't mine
After you download their software, bench your computer. From there go to whattomine.com and enter in the values returned from your bench along with how much power your computer uses and how much your electricity cost is and see if it's worth mining with that computer.
