Make sure your BIOS is up to date. Also, I would suggest you install both the Dell chipset and video drivers for your rig. Sometimes Dell tweaks peripherals in such a way that you need to use their drivers for optimal performance.
If the error continues after following these steps, I suggest you contact Dell. The error you are seeing is fairly common and updating drivers usually takes care of it.
Yes, I will call Dell and try to get a solution. Keep updated if anything happens
