problem assigning CS pin to another digital pin

[/c int CS_pin = 35;//chips select pin is pin 35
 int pow_pin = 8;
 void setup()
  {
 
  pinMode(35, OUTPUT);
  pinMode(pow_pin, OUTPUT);
  SPI.begin(); 
  Serial.begin(9600);
  Serial.println("initializing card.....Please wait");
     pinMode(CS_pin, OUTPUT); //chip select pin as output

//chips select pin is pin 35

What chip? If the chip is hardwired to a pin, you can't change the select pin.

So, you need to provide a lot more information, including ALL of your code.

What PaulS said and:

 int CS_pin = 35;//chips select pin is pin 35
 int pow_pin = 8;
 void setup()  {
   pinMode(35, OUTPUT);//**********//chips select pin is pin 35
  .........
   pinMode(CS_pin, OUTPUT); //chip select pin as output

Why are you doing this twice?
