Arduino Nano v3 Problem - I already checked posts about it

hi guys,

i have big problem nano v3, it's clone ft232rl (real chip), not cheap chinese ch340.

ways connect:
way 1 (don't work):
when connected computer, rx , tx leds blinking , blue led (power led) on not @ maximum of brightness.
the nano doesen't appear in device manager.

way 2 (work):
i power nano 5v regulated, arduino uno (wiring gnd or vin enough, didn't undestood why).
then plug in cable nano computer , work.
and power led got super brightness, more way 1.
i can upload sketchs, com port appear.

so found way nano working it's boring need power source it.

basic troubleshoot, did these things:
- tried many usb cable
- shorted test pin gnd, on ftdi chip
- burnt new bootloader
- try computer

thanks in advance,
yeko

your usb connector on nano bad. nothing can do.
