Yes you are right after unplugging USB devices it is working now .
problem is that i need both ( at least once) and keyboard/mouse to configure WIFI adapter . how can i do this now . Will overclocking help her in any way .

your RPi simply do not have enough juice to run and feed the USB devices.
My recommendation:

• PSU 1A(1000mA) or above
• always use self powered USB devices or connect via self powered USB Hub only! Not direct to RPi
