Errr... can we first know what you video card is? If you're not sure, and you're using Windows, press the Windows Key + R, type in "devmgmt.msc" and press Enter.
You'll see the Device Manager window. Look for something saying "Display Adapters", then click on the plus sign beside it. You should see the name of your video card appear.
Next time, please post your question only once on this forum. We all try our best to answer questions here, so be patient!
