pls help me what can i do
thanks..

why not look for a decent, proven good setup in this forums wiki?
wiki/doku.php?id=connecting_the_board

a) esp8266 is not 5V tolerant, so why jumper 5V?
b) USB/serial not fit enough to power ESP, 3V3 supply missing

If you want to mess around with other ppls flakey setups, go ask them for help.
