Upgrading a video card. How?

how do you take out your video card and replace it with a new one?|||Be sure to power off the pc and unplug it from the power source before doing ANYTHING! make sure you are grounded. best place is a hardwood floor or laminate. Standing on carpet and sliding your feet around creates static electricity. touching the case itself will generally ground you to the case and prevent static electric discharge. open up the side of the case and look for your video card. If you don't know what it looks like you shouldn't be doing it at all. next remove the screw/screws holding the card in place from the back of the pc. Next you want to push the tab holding the card to the board down to the unlocked position. Remove the card from it's slot and insert the new one. Lock the tab that holds it to the mobo and put in the screw that holds the card into the case. You should know the rest. The computer should recognize the card immediately. Make sure to get all the latest drivers and directX. DO NOT INSTALL DIRECTX 10 ON AN XP COMPUTER!!!!! This will cause crashes all over. If you need help finding the drivers or directX look to the manufacturer's website.|||you take out the screw outside the case and you pull out the card inside and put the new one in.
