When I turn on my computer, it states that there is no boot device available. I ran the diagnostics and it states that there is no hard drive available. How do I fix this problem?
You shoudl first go into your BIOS settings and ensure that the HD is registered there, compltely.
Then with the power off, open the CPU Case and look for the HD. Ensure that the jumpers are set to MAster, and that all cables are plugged in proberly and firmly. and I mean at both ends of the HD, the HD itself, and the cable to the motherboard/disk controller.
Then you should be sure that your HD didn't somehow get clobbered, such thta the disk is wiped clean, or that the critical Windows boot files are missing. If so, if you had created a boot disk for such an occurrance, then restart and hit F5 or F8 immediately after the power comes on, until you get a menu for boot. Find the option to allowyou to use boot repair and system repair on your computer.
If nothing works, then it may be necessary to start fresh and recreate your sytem from scratch.
I wish I could bring better news.

Do a scan disk.
Seems issue with the drive.

Hey! Nice Computer! ( At least while it was working! Specifications show some high-end hardware parts)
Steady amber light on the Power On light, means a bad power supply.
The Dell XPS 420 uses the standard ATX style of power supply found in 90% of computers out there.
(Personal computers. Not the Cray Supercomputers!)
This is Dell Support, and the User Manual - Removing and Replacing Parts - part of the manual,

From Me:
1) Computer unplugged from power, computer case open. TOUCH the metal frame BEFORE you reach inside.
Your body carries Static electricity.
Static will fry out computer hardware components.
You won't see it, or feel it.
Computer unplugged from power, you are safe.
Touch the metal frame Before reaching inside, your computer is safe.
Should you get up for any reason, walk away, then return, Touch the metal frame again)
You either have a 375 Watt, or a 425 Watt power supply.
I would recommend a power supply with more Wattage, and more Amp's on the 12 Volt power rail.
The Dell XPS 420 comes with an Intel Core2 Duo processor, or an Intel Core2 Extreme processor.
These puppy's can use a lot of power when gamin', or other intense programs are being used.
The Nvidia GeForce 8800 Series of graphics cards offered, use a lot of power when maxed out.
The motherboard with the Intel X38 motherboard chipset, uses a lot of power.
I would recommend a 600 watt power supply for a replacement.
My recommendation would be an OCZ StealthXStream 600W
Why?
1) If the temperature of this PSU is kept under 118 degrees Fahrenheit, the PSU can put out 728.8 Watts reliably. (47.9 degrees Celsuis)
2) It has Four - 12 Volt power rails.
EACH power rail can handle 18 Amps.
That's a total of 72 Amps!
3) It has all the power cables you'll need.
A) 20 + 4-pin ATX motherboard power cable
B) 8-pin 12 Volt power cable (8-pin EPS)
C) 4-pin ATX power cable
D) SATA power cables [ 3 ]
E) Peripheral power cables, (4-pin Molex) [ 6 ]
F) 6-pin PCI power cables. [ 2 ]

SOURCE: When i try boot my dell xps 420 it states that
A boot device stores your operating system (i.e. Windows), and is usually your hard drive, but can be any storage medium such as a floppy, usb flash drive, or even a cd rom. When you turn your computer on, your motherboard looks for your OS on any of the storage devices specified in your bios, in the order specified to look first (Ex. Boot order: 1. CD-Rom, 2. Floppy, 3. Hard Drive, 4. Network). Your Dell is telling you that it can't find Windows on any of these devices. Most likely cause is that your hard drive stopped working, your Windows boot.ini file became corrupted, or you have a USB device plugged into your computer, and it needs to be unplugged before turning on your computer.

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location, if applicable.
Ensure that the processor power cable is securely connected to the system board.
This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.
