Problems with my RPG app

I'm working on an RPG program that can be used as an engine; basicly I finish the engine and use it's functions in a different program with all the fluff. The problems right now are:
1. It doesn't seem to be very random. Hmm...
2. If the damage isn't enough to kill you or the monster, it doesn't take down any hp, just leaves it like it is.
3. A buncha other problems that seem to pop up randomly.

Here's the code:

Code:

 DWORD dwConSize;
 HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
 GetConsoleScreenBufferInfo(hConsole, &csbi);
 dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
 FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
 GetConsoleScreenBufferInfo(hConsole, &csbi);
 FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
 SetConsoleCursorPosition(hConsole, coordScreen);
} // End crud WinAPI.

I just added some comments and I always indent/space it as good as I can.

Here are the random functions i use, perhaps it can help you?

#include <stdlib.h>

int getrandi(int low, int high)
{
return low+rand()%(high-low+1);
}

float getrandf(float low, float high)
{
float range = high - low;
float num = range * (float)rand()/(float)RAND_MAX;
return( num + low );
}

double getrandd( double low, double high ) {
double range = high - low;
double num = range * (double)rand()/(double)RAND_MAX;
return( num + low );
}
