Hi Kate,

Welcome to the Community.

I would recommend you to update the BIOS and the Chipset Driver of the computer.

To update the BIOS please click the link mentioned below which will take you to the driver’s website: http://dell.to/Qnizfs. Enter the Service Tag of the computer and choose the Operating System installed on the computer. Please update the latest version of BIOS available.
