Some USB ports were affected when they upgraded to a newer operating system without installing a USB driver for it. Try downloading the right chipset driver and OS again at Dell.

Do you still have this problem if you boot into safe mode? If not, then there is a problem with one of your programs interfering with usb drivers.
If it does still happen in safe mode, then you may need to re-install your drivers. To do this, boot up normally, go to Start/control Panel/System/Hardware/Device Manager. Find your USB section, and right-click the USB Root hubs, and uninstall them. Then reboot, and windows will then detect the usb ports, and reinstall the necessary drivers for proper operation.
Hope that helps.
Cheers from NZ

D400 is not booting up from usb

Is your system set up to boot from USB? What is attached? A flash drive or an external cd/dvd drive? If a flash drive, was the software on it created to be bootable? Is this the first time you are trying to boot from USB? Please provide more details.

You have to be absolutely sure you are downloading the correct display drivers for your system. The dell installers are very picky.
There are 2 video drivers here is the link.
