I am including chipset and video drivers for Windows 8 64 bit, you may need to look for support.dell.com for other versions of drivers if another operating system has been installed. I am looking forward to reading your reply on when this started happening and if the drivers helped. Intel G41 Express Chipset Driver For Windows 10.
