Indicates a bad Power Supply.

Weak voltage power rail

[There are three main voltage power rails;
3.3 Volts, 5 Volts, and 12 Volts. All are DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.

The Power Supply is a converter. Converts 100 to 240 Volts AC, from your home, or business; and turns it into the low DC Voltages stated above.
Japan - 100 Volts AC
US - 120 Volts AC
Europe 240 Volts AC
Australia 240 Volts AC,
etc ]

http://en.wikipedia.org/wiki/Dell_XPS_730x

Indication is that it uses a 1000 Watt power supply.

Power Supply Unit (PSU)
"The Dell 1000 Watt PSU is an oversized (taller and wider) than standard ATX power units, although it does use the standard ATX bolt pattern to bolt it to the chassis."

http://en.community.dell.com/support-forums/desktop/f/3514/p/19032409/19155395.aspx

!O_O!

According to the specifications, the Dell XPS 730 comes with two Nvidia GX2 9800 graphics cards, and they are connected together using SLI.

[Scalable Link Interface,

http://en.wikipedia.org/wiki/Scalable_Link_Interface ]

One Nvidia GeForce 9800GX2 needs a minimum power requirement, of 580 Watts.
Using two in an SLI configuration, requires at least 850 Watts.
If your computer has an Intel Quad Core processor, 1000 Watts is about right.

Power for the;
Motherboard, Processor, optical drives, Card Reader, Ram Memory, and two of the 9800 GX2's.

Since the Dell XPS 730, does have provisions for using a standard ATX power supply, this means any Ol' ATX power supply can be used. Mounts (Bolts) right up to the computer case metal frame.

We are looking at a 1000 Watt power supply. Can you say Ouch?

Do you have access to a multimeter? I can guide you in testing the three main voltages.
This way we can determine if I am correct, and won't waste your hard earned money.

(An economical multimeter can be purchased for as little, as $5 to $12. Available in a multitude of stores. An auto parts store is but one example. I have seen them on checkout aisles in major discount stores, also )

Computer also needs to be clean inside. Especially the Processor fan, and the finned Heatsink.
Use a can, or two of compressed air for computers.
(Attach the plastic straw, break the plastic lock tab off of the top of the nozzle)

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.

Computer ON a table, computer Unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again, upon your return.

One bad or faulty lead connection can cause a computer to continue restarting on a cycle or to shutdown or fail to detect your hard drive.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty


if its a 40 pin flat ribbon type it will be the first to fail


make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty


even something as small as a faulty electrical fan and its lead can cause you problems

computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error


make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free


restart your computer then reinstall it this should activate found new hardware wizard


Hope this helps.

SOURCE: XPS 600 serious Boot up Problems!

sounds to me like the fan is on the way out ,and if the cpu gets too hot the pc will shut down.
check that the fan is not obstructed,clean it if it is full of dust, replace it if it is not working as it should.

also listen to the power supply fan, is it working ok,this could cause the same type of problem but for different reasons.

good luck
Terry

SOURCE: My dell xps wont start properly, yellow blinking light

I have an HP that does close to the same thing. Mine goes into a 'Perm-Sleep' mode that I can't seem to pull it out of. I have to remove the battery, then unplug the power adapter, not in that order. Leaving it in this condition for about a minute so that all the power stored in the RAM goes away. This is the same as holding the power button down for 10 to 15 seconds until it completly turns off, sometimes referred to as a 'Cold Boot.'

Once I have powered it down I have to go into the control panel and select the power settings and make sure that hibernate is not an option. If you close the lid on the laptop and the systems goes into a sleep state, it may be configured to go to hibernate after, say an hour or when the battery gets close to being drained. My computer does not like to come out of hibernate and I have to Cold Boot it, so I just don't let it go into a hibernation in the first place anymore.

SOURCE: 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 Dell XPS 730 needed a new CMOS battery I changed this but now it wont post get no beep errors and it doesn't get to the DELL screen. There is power everything lights up and fans start going but no...


I believe you have used the wrong type of CMOS battery. Try putting the old one back in and see if it will boot. If not the CMOS NAND chip may be broken. If this is the case contact Dell and order a new one.

My XPS 200 keeps shutting down and power light blinks


During when does your computer shutdown? Please check the diagnostic lights at the back as well which ones have light on it during the time it would shutdown.

Since you said that the light is blinking yellow it just says that your power supply is running outside its normal operating range. So most likely you would need a change of power supply. Maybe a higher wattage would be better.

Dell XPS 730 no video, not bios, fan running hard


Fist touching anything on the motherboard without a anti-static strap can kill the motherboard.

The fan running at full speed is no big deal. If you took out the video card
how do you expect to see anything on the monitor.

You need to plug the monitor you have into a working computer, this will rule out the monitor. If the monitor died, you did all this for nothing.

Now unless the motherboard has onboard video you have to put the card back in, if it does have onboard, even without the drivers installed you still see the post, because windows will let it run at post, and with the video card, it will still show post without drivers.

Do this,check monitor, try both ports and post back and tell us whats
going on.

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.

Hi,
Kindly un-install both the drivers for blue-tooth and wireless card from your computer. Just right click on each driver in the device manager select remove or un-install. Restart your computer and re-download the drivers from the dell support site.


www.support.dell.com

Note: dell support site would only contain drivers , for your xps system h/w that came from dell. if you have attached the wireless and blue-tooth later , you might need to download them from manufacturer website

Dell XPS M140 laptop shuts off after powering on


Most laptops that I have worked on that power off that quickly turned out to be an overheating problem. Is the cooling fan running for the brief period that you can hear the hard drive before it powers off ? If the fan is running another potential resolution might be to remove the processor and apply new thermal paste.
