If it's under warranty contact the manufacturer first. Uninstall the drivers with DDU in safe mode and install the drivers. Search the internet for problems with the error code, it sometimes is error 43. That is either a hardware problem with the card or sometimes can be fixed with flashing the exact same manufacturer's BIOS the card came with and also run an AMD pixel patcher program. You can find guides online, be very careful as you can damage your card.
