How to install a graphics card

How to install a graphics card: upgrading your PC with a new GPU First thing's first: you need to find where your graphics card is going inside your computer. 

Depending on your motherboard, you may have just one PCIe slot or you may have many. Generally, you want to install your graphics card into a PCIe x16 slot. There are two parts to identifying a PCIe x16 slot. First, look for the longest PCIe slot on your motheboard. Slots come in x1, x4, x8 and x16 sizes. If you're not sure, you can compare the slot length to the length of the connector on the bottom of your graphics card. 

Next, confirm that the slot you've found is a true x16 slot by looking for a text indicator on the motherboard itself. Some PCIe slots may be the size of an x16 slot back actually have fewer PCIe lanes, which can limit performance. For instance, we have a Micro ATX motherboard with two PCIe x16 slots, but one is a true PCIe 3.0 x16 slot while the other is actually a PCIe 2.0 x4 slot offering restricted bandwidth but support for longer add-in cards. 

 Once you've found the correct slot, you should make sure the PCIe slot is in its open position. Some slots have a small clip at one end that can flip up and down. Flipping the clip down will unlock the slot. Other slots may have a clip that moves sideways. It will simply flip out of the way when you install the GPU, and then it will lock back into position. 

You also need to remove any expansion slot covers on the back of your computer case that line up with the slots your graphics card will fill. On some cases these will screw off while others may snap off. Now you're ready to put the graphics card in. When holding the graphics card, avoid touching the PCIe connector or exposed portions of the PCB. 

First, line up the graphics card with the PCIe slot. Then line up the end of the graphics card with the open expansion slots on the case. Make sure the end of the graphics card's I/O shield is clear of the motherboard and not pressing into it. Lower the graphics card into its PCIe slot. It should not take much force. You may hear a click when the lock at the end of the PCIe slot flips into place. If you don't hear anything, confirm that the lock is in its closed position.
