SEAGATE 500 GB H.D.D NOT DETECTING IN BIOS AND IT HANGS THE PC.
ALSO AFTER OPENING UP I FOUND THAT THE SMOOTH IC (AS WRITTEN ON THE IC'S) IS LITTLE BIT HOTTER THE OTHER IC'S. HOW CAN I FIND THE BAD COMPONENT.

SEAGATE BARRACUDA 7200.11 500 GB

It does not sound like a PCB problem.
Most likely you have internal damage to the drive.

The drive is spinning ok and there are no sounds

I would rather buy a new h.d.d then buy a logic board.

hi,
98% sure it's no the PCB problem. and you can check the condition with MHDD. or you can swap it to similar drive as well. check the voltage of the PCB may be hard to do. as it may have much difference on your drive.

the ttl to serial adapter is working

How do you know the adapter is working? If you connect the Tx and Rx wires together, can you see characters being echoed on your screen when you type? If so, and if you now separate the Tx and Rx wires, can you still see echos when you type?
