If this is a new PC and under warranty, you should contact Dell Tech Support ASAP.
Looks like this PC only has USB3.1 and no USB2 ports. USB3.1 should be backwards compatible with USB2 devices.
Was Win 7 installed on the HDD while it was installed in this specific PC or are you trying to boot from a drive "borrowed" from some other PC? A borrowed drive isn't going to boot the system unless the other PC has exactly the same hardware, especially the chipsets.
What happens if you boot from a bootable USB stick or bootable optical drive? Do the PS/2 ports work?
If this isn't a new PC, you might try resetting BIOS to the default settings by removing the motherboard battery and pressing/holding the power button for ~30 sec before reinstalling the battery.
(BTW: You posted this in the XPS forum, but the Precision forum is here.)
