Go to your computer or motherboard manufacturer for new updated drivers. Go to the manufactures of your cards to get their latest drivers. Drivers are free but some sites will make you pay because many people do not know any better.
If you have a Dell or other prebuilt just go to their website and find drivers via the model of your computer under support / downloads.
Do not know your motherboard brand? CPU-Z
