I myself have some esp8266 chips that won't even boot up without adding capacitors.

thanks , i didn't pay attention to the VCC , could this also cause my second problem which is the strange marks on the serial monitor of the arduino IDE when i use the software serial ??

I have noticed that software serial can not reach 115200 bauds and creates strange looking text. 9600 bauds works always, but the other speeds you just have to test.

On the other hand it is normal that you get meaningless text to serial monitor when an ESP8266 chip reboots. I don't know why this happens but every chip seems to create this "garbage" . You just have pass this and wait for actual data.
