Bitcoinclient isnt working

[ASQUADLEADER]

Im nearly sure that my problem is just totaly simple, but i have no idear what the problem is.
My GrKa is an R9 280X Tri-X by Sapphire and my cpu is an fx 6350 just factoryside overclocking. I hope this helps. I gues ists sometihng with java, because minecraft is alsow not runing properly. I got the newest Version of java and im using bitcoin client v1.6.1 .

This is displayed if i hit the engin on button:

2014.10.12 [19:24]  No devices to start! Please connect mining hardware to USB port(s) and use devices menu to probe for them.

thank you for all answers.

What are you actually trying to do?

If you are trying to mine, it isn´t really the bitcoin client you want to have working, but a miner (eg cgminer).

You need to be more clear on what your problem is exactly, what steps you've taken to fix it and what errors you're getting. Also, mining Bitcoin with a graphics card is going to make you lose money. Buy a dedicated ASIC miner or buy Bitcoin and hold.
