IF ALL REQUIREMENTS ARE DONE THIS IS THE NEXT STEP:
Make sure you insert 1st the VGA Cable in VC
Now Power On your PC and go to BIOS the make sure your Init Display first is set to ONBOARD now Save and Exit then turn off your PC .
Move your VGA Cable to Onboard VGA PORT then POWER ON your PC
After Power on go to BIOS for the Last time and look for IGX CONFIGURATION to set the UMA FRAME Buffer SIZE Take note to decide what to choose, if you got 1GB in your Video Card set it to 1024mb and if your Video Card is 512mb set it to 512mb after that SAVE and EXIT
the Last thing to do is to go in AMD VISION ENGINE CONTROL CENTER choose advance view to gain access to Performance TAB > and the AMD CROSSFIRE > check the box that saying ENABLE CROSSFIRE.. then restart to take effect..
