Thanks guys for your help, Ive got it working now.

This is what it should have been...

//---- file: cpuspeed.c ----

#include <windows.h>

unsigned __int64 start, stop;
unsigned __int64 nCtr, nFreq, nCtrStop;

int CpuSpeed(void)
{
    QueryPerformanceFrequency((LARGE_INTEGER *)&nFreq);

    __asm__(".byte 0x0F");
    __asm__(".byte 0x31");
    __asm__("mov %eax,_start");
    __asm__("mov %edx,4+(_start)");
	
    QueryPerformanceCounter((LARGE_INTEGER *)&nCtrStop);
    nCtrStop += nFreq;
    do
	{
        QueryPerformanceCounter((LARGE_INTEGER *)&nCtr);
    } while (nCtr < nCtrStop);

    __asm__(".byte 0x0F");
    __asm__(".byte 0x31");
    __asm__("mov %eax,_stop");
    __asm__("mov %edx,4+(_stop)");

    return ((stop-start)/1000000);
}
