I have an Arduino Mega 2560 board. The problem is, could not identify in the device manager and as well as in the arduino IDE. So, I updated my driver and checked, it was not detecting.
I tried with other Arduino Mega 2560, they are working just fine, except this one.
When I give USB power to the Arduino Mega 2560 board, the BUILTIN_LED blinks rapidly. This is the indication I inferred. Does this mean the Arduino boot loader corrupted ?
If arduino boot loader got corrupted, at least it should to get detect in the ports, right ?
So, is this the problem with the other chip (USB to serial converter), if yes, Please Let me know your thoughts.
It sounds like you were printing something and have the serial port flooded. Start by removing everything connected to the arduino then try this:
Take these steps: Power off the board completely (remove the USB cable). Hold down the Reset button,
keep it held down (or, run a jumper wire from the RESET pin to the GND pin). Still holding down Reset,
reconnect the USB cable. Start uploading a sketch that does not have this problem (I use the Blink sketch).
I have seen this happen several times when I flood the serial output. An indication is the tx light is on.
Secret do not keep the console constantly busy printing.
Good Luck & Have Fun!

No No, I am not printing anything nor doing any serial out. The Arduino is not getting detected when connected to PC (All the driver are upto date, and other arduino boards are getting detected and works fine).

I tired this, No luck. Still behaves the same. Any other thoughts on this ?
If there is no port showing, the problem is a hardware issue (damaged board, or bad cable(there are a lot of bad cables making the rounds)), or a driver problem. The bootloader isnt involved until after you start uploading - a problem with the bootloader cannot keep the board from detecting (on classic boards like nano/pro mini/uno/mega - on boards with native USB like leo/micro and some of the ARM-based boards, it can)
If it's a clone, it probably doesn't use the 16u2 as serial adapter like official boards do (so the ide does not include the drivers). Look at the markings on the black chip near the usb port, it will likely be a cp2102 or ch340g, Google that part number and your os and os version, download and install, and see if that fixes it.
