Dell xps 420 black screen after intel

Corrupt files

more than likely bios isn't letting it boot, i'd make sure the fan bearing hasn't gone out, if it has you can order a new one

From the description the LCD screen will need to be replaced, first! hook a spare monitor to the video output on the back, if picture okay! the problem is the above mentioned, but if both screens show the same symptom it is the video graphics card.

You might need a new Graphics card and a 400 w power supply. also, try cleaning it (the fans and HS's

see if this info helps narrow down the failure

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 ]

Do a scan disk.
Seems issue with the drive.

Same with my Dell Vostro 420. At this rate I will just buy a new PC as I am wasting too much time on this. We tried usual stuff like cleaning inside, making cooler, removing certain virus software, still no luck. I have to restart 4 times a day and keep saving material. Can only restart by turning it off by pulling out power socket.

go to disk management and inicalize the drive

Try Uninstalling them using the add or remove programs and then try reinstalling them again
