AMD graphic code 43 error?

Nowdays the laptop doesnot take the drivers normally when we boot/format the computer with windows 7 or windows 8.AMD graphice code 43 is error is due to this problem.The driver is not installed properly or driver is out of date.You can download the driver from the different site but I suggest to download from the geinue sites like if you laptop is of Hp gp to hp.com and download the drivers.
After downloading the drivers
1st install intel driver and then install amd driver. Now restart your computer.

write a program to add two matrix using array??

#include<stdio.h>
#include<conio.h>
main()
{
int x[3][3],y[3][3],z[3][3],i,j,k;

printf("enter the first matrix");
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
scanf("%d",&x[i][j]);
}
printf("enter the second matrix");
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
scanf("%d",&y[i][j]);
}
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
z[i][j]=x[i][j]+y[i][j];
}
printf("the matrix addition is");
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
printf("%d\t",z[i][j]);
printf("\n");
}
