user23506: So, I recently bought an Arduino Mini (5V, 16MHz), and a USB to Serial Converter.
Provided are the links to both the products:
Arduino Mini,
USB to Serial Converter
Now, I tried programming the mini by connecting the pins in this order:
Rx -> tx, tx-> rx, VCC -> 5V, GND -> GND, DTR -> DTR
The computer detected the USB to Serial converter after I installed the drivers manually. However, the Arduino IDE failed to program the Arduino Mini every single time, even after I swapped the TX, RX pins.
I tried to program the Arduino Mini using an Arduino Uno (I removed the onboard Atmel Atmega microcontroller on the Uno before programming). I connected the pins in this order: TX->TX, RX->RX, 5V-> VCC, GND-> GND, RST -> DTR. From the IDE, I chose Arduino Pro Mini (5V, 16Mhz).
The Mini was programmed successfully this time.
My question: What was wrong with the USB to Serial converter? Why couldn't it program the Arduino Mini with the USB to Serial Converter? 

user7924: Try to reset manually just after compiling end

user-1: As you have said the Arduino Mini seems to be fine and the USB to Serial Converter seems to be working too.
This might be a crazy idea but this might work
try connecting the boards like this,
TX -> TX  and  RX -> RX
I'm not totally sure, but this might work.
