Dell XPS 420 won't boot at all not even a BIOS screen

Dell XPS 420 won't boot. Can't even get the chance to boot into safe mode. Power light comes on. Fan starts in then end only the lights 1,2,3 are on. I know these number lights mean something to Dell techs, but I don't know what they mean. Any ideas? Hopefully somebody knows thecodes and can tell me right away if this is a motherboard, video card or power supply problem. I figure it has to be one of these based on hot it's acting.

To my own understanding, the system file was attack as well as corrupted by the virus, so that the virus would not allow the system to boot accordingly. Therefore, i suggest that the system will be formated if the infact is much, or reinstall the window.

I have Dell XPS 420 , with windows home server running for some time. I tried to insall/upgrade RAM from 3 gb to 6 gb. So, i found the right RAM (2x2GB) and removed the two old 512 mb from the slot and...


According the the dell specification you can only install up to 4gb, so I don't understand you saying that you were upgrading from 3gb to 6gb. Make sure that all the ram that is installed is of the same brand and speed (667 / 800 MHz Dual Channel Dual DDR2 SDRAM). The fact that it is saying no boot device also would suggest that it is possibly something wrong with your harddrive, whether it was corrupted or damaged while you were changing the RAM, if you have a spare harddrive try installing and booting from it. If that doesn't work it could be a motherboard issue, which the BIOS should be update, all the jumpers on the board should be checked etc. Its rather hard to diagnose a problem such as this, and the fact that after you installed the new RAM, even the old RAM would not work, suggests that you may have damaged something while messing around in the computer.

I have a dell xps 420 and its infected with some form of spyware. my issue is getting it to run in safe mode... i have no clue on how to do this. most site explain the use of f8 at startup and it should go...


To enter safe mode you must press f8 right before the Windows logo screen. In my experience the best way to achieve this is to tap the f8 button repeatedly when you turn on the computer. F8 is the correct button for Windows operating systems, the guides were right, you might have just not pressed it at the right time.

When i try boot my dell xps 420 it states that there is no boot device available. Why does it say this?


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.

My Dell XPS 420 will not turn on. Power light


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,

http://support.dell.com/support/edocs/systems/xps420/en/OM/HTML/parts.htm#wp1466871

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 ]

Not advertising for the above website, nor the PSU manufacturer. Recommendation supported by personal preference, and experience.

My xps 420 pc desktop wont boot. Shut it down last


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.

Xps 420 keeps freezing or going to blue screen


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.
