Remember if you are going to remove the 4600 card, go into bios first and turn on the onboard gfx before turning off the pc and removing the 4600 or you might not get any display at all! I forget to do that sometimes and wonder well it used to work then had to put card back in, bios change settings save, turn off and remove the card a 2nd time lol Joys of computing as they say!
Okay thanks,i just downloaded AMD autodetect and it says my graphic hardware is HD4XXX series so it means its detected.
So the process to change those settings in the bios do work. It should technically auto turn off the onboard when a card is fitted but sometimes they dont and you end up with just onboard or two cards showing in device manager. At least its being detected so when you get the better gfx card you know how to change the bios and you should be good to go with the new graphics.
