Try and reset your CMOS and see if it helps.
If you're not sure how, then unplug the power cable from your PC, then take off the side panel, on the motherboard is a set of 2 or 3 pins to Clear the CMOS (reset the BIOS) all boards are different, so there is no set location for the CMOS pins, if you're unsure, just remove the battery from the motherboard for about 30 seconds, then replace it ("+" facing up)
But you need to make sure your PS is not plugged into any external power source while you're doing this or you risk deleting your BIOS
Hope this helps in some way.

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,
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
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 ]

Dell has a program called zztop, you can find the utility here:
there is a hidden partition ( you cant see it in windows nor will you be able to see it in most partition managers) that holds your original OS. Running zztop will put this image back on your comptuer.

If your system's power light blinks amber, it means the computer is receiving electrical power, but an internal power problem might exist.
Do the following to tackle this issue:
Here are links with pictures to assist you in opening the system and reconnecting the internal cables.
Please follow safety instructions before you perform these tasks. Here is a link, which gives you complete safety instruction.
Next is to see the system board design. Here is the link.
and if you wish to research a bit more here is the link,
Here you will find complete manuals for further research
If this does not resolve the issue, then the motherboard or processor is faulty and you need to get it replaced, so if your system is within warranty why pay extra, get it replaced from Dell. Else contact a local tech and he'll help you out.
Please rate as per the assistance level. Thanks :)
