Well, we do not know. Provide your operating system and version, and your system or motherboard model number and manufacturer.
And, tell us what driver you tried to install. Provide the link.
Also, have you tried the driver from your system manufacturer's website?

Well, if the driver from the gigabyte site is producing these problems, I would go back to gigabyte and ask why. They are your first line of defense. There may be some hardware issue that they are aware of, or perhaps you need the latest version of their bios.
That said, this is your processor:
