I'm having Intel(R) Pentium(R) 4 CPU 3.00GHz Processor with 2GB RAM. While trying to install Windows 8.1 Pro 64-Bit i gave me an error saying that the processor is not compatible with Windows 8.1 Pro 64-Bit .I checked the system requirements and found that my processor doesn't support PrefetchW but all the other requirements are supported.

HTT * Hyperthreading enabled

X64 * Supports 64-bit mode

NX * Supports no-execute page protection

PAE * Supports > 32-bit physical addresses

SSE2 * Supports Streaming SIMD Extensions 2

CX16 * Supports CMPXCHG16B instruction

PREFETCHW - Supports PREFETCHW instruction

Note : '*' means it's there(supports) and '-' means it's not there(doesn't support)

I know i'm asking a poor question. But i want my old processor to run Windows 8.1 64Bit anyway. Is there any way to run Windows 8.1 64 bit without PrefetchW support?

no, this is not possible. The only way to install Windows 8.1 on this CPU is to use the 32Bit (x86) Version which is recommend when only using 2GB of RAM.
