I have noticed that while playing the 8 bit games or 16 bit street fighter, I have crashed P4 processor as well as Core 2 Duo. Once it may be co-incidence but the same thing happened to me as well as one of my friends neighbour.

There aren't 16 bit or 8 bit games for PC so I assume you are running a SNES emulator or something. It's probably just bad emulation software and not a problem with your PC.
There are 8-bit and 16-bit games for the PC if you go back far enough into the 1980's and 1990's. After all, the first home PC did not use a 32-bit operating system.
PC games have never been refered to as 8 bit or 16 bit games to my knowledge, and there has certainly never been a 16 bit version of Street Fighter released for the PC. And yes I've heard of DOS smartass, I still have my DOS 5.1 disks :P
You can use DOSBOX to emulate most of the old PC games out there.
