1) If you have been powering on/off alot, then power supply may have flipped. Wait a while to let it cool down and try again.

2) Your motherboard may be shorting underneath, so loosen mounting screws and lift the board slightly and try to power on.

3) You are shorting the power-on jumpers or have the power-on button connected to these jumpers.

Why is dell optiplex 780 lights 1 & 3 ok and power button amber?

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard.
Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

I have a graphics card as i want to play games on my pc.

If you do have one it will be a lead comming from the back of the power supply case. If there is not one there you will have to upgrade your power supply to a more modern one with more power and more connections.

You could use one of these: Adapter But only if you have a spare Molex 4 pin lead the same as the one that powers the hard drive and CD/DVD drives. Even then the power supply has to be able to supply enough current to ensure the graphics card gets enough without draining the supply for other things. It should tell you in the instructions for the graphics card how much it needs/uses.

My computer won't start up and is blinking yellow. How do I fix it?

An steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Hi! I am running Windows XP 64 OS on a Intel D975xbxlkr motherboard. I need to replace the pci express graphics card. One that will be compatable with the OS and motherboard. I am not gamer Any...

Everything on the Intel D975XBXLKR motherboard is 64-bit. The Processor, and Northbridge chipset included.

The Northbridge chipset handles the Processor, Ram Memory, and high-speed graphics.

AGP and PCI Express is high-speed graphics.
A graphics card plugged into a PCI slot (White) or using Integrated (OnBoard) graphics is NOT high-speed graphics.

The Northbridge chipset for an Intel D975XBXLKR motherboard is an Intel i975X.
(The i stands for Intel)

ALL PCI-Express graphics cards are compatible with a 64-bit O/S.

What you may be concerned with, is whether the PCI Express technology used on your motherboard is PCI Express 1.1, or PCI-Express 2.0

It is PCI-Express 2.0 technology that is used.

[Doesn't matter anyway. PCI-Express 2.0 technology is Backward Compatible with PCI-Express 1.1 technology.
A graphics card based on PCI-Express 2.0 technology will work on a motherboard with PCI-Express 1.1 technology.
You just won't get the full capabilities of the graphics card.
You probably won't notice either ]

A recommendation for your perusal;


Yes this is a type of gamer graphics card, and I read your requirement.
My argument is the quality for the price.
Even if you do not game your graphics will be superlative.
Excellent graphics on a computer makes a world of difference.
This graphics card will work with a 350 Watt power supply.

1 out 50 times I turn on my Dell Dimension E520 there is no signal to the monitor. I have tried to install a new PCI express card instead of using the integrated graphics but the result was the same e.i no...

The problem is the Power Supply. Weak voltage power rail.

You've taken the right steps with your diagnosis.

1) Start with the monitor cable. If removable use a known to be good monitor cable.
Checks okay, go onto the graphics 'engine' of the computer.

If the monitor cable is not removable, use another monitor, and cable for a test.

2) If you are presently using Integrated Graphics the next step in diagnosing is to install a graphics card.
See if the problem is the Integrated Graphics 'engine'.

[ Just to add:
Intel GM X3100 is the graphics 'engine'. It is integrated into the Northbridge chip of the motherboard chipset.

Intel G965 chipset is the motherboard chipset. The Intel ID number on the Northbridge chip is 82G965.
The Southbridge chip is an Intel ICH8, or ICH8R, or ICH8-DH,

{Chip and Chipset are slang terms for I.C.
Integrated Circuit, }

The Northbridge chip handles the Processor, Ram Memory, and HIGH-speed graphics.
AGP and PCI Express are High-speed graphics.

A graphics card in a PCI slot is not High-speed graphics.

The Southbridge chip handles the slower capabilities of a computer.
PCI and Integrated Graphics being two of the slower capabilities.
SATA, IDE, USB, and Ethernet, are also some of the slower capabilities of a computer,

CPU = Central Processing Unit. Another name used is Microprocessor, or Processor for short ]

3) Power Supply.
Weak voltage power rail.

The Power Supply has enough power to light LED lights, and maybe spin fans, but Not enough power to turn the Processor on.

A) ALL the LED lights on at once will consume less than 1 Watt of power.

B) EACH fan consumes 2 to 3 Watts of power.

C) A typical Processor can consume (Maximum) 51 to 125 Watts of power.
Depends on what Processor it is.

The Dell Dimension E521 desktop computer's motherboard, has an LGA 775 processor socket.
(Processor has the socket holes, processor socket has the pins)

The Intel processors that can be used in this processor socket, can be an Intel Pentium 4, (Version that uses an LGA 775 processor socket), Intel Pentium D, or Intel Core2 Duo, AND Intel Core 2 Quad, with a maximum FSB of 1066MHz. (If the BIOS version will support Intel Core2 Quad processors)
{Front Side Bus of 1066Megahertz}

Wattage consumption can be as much as 105 Watts.

Do you have a KNOWN to be good, compatible Power Supply available, to use as a test unit?

{Compatible being that the Power Supply case fits, (ATX), has the right amount of power cables, and the correct power cables. (Needs to have a 24-pin ATX main power cable, and a 4-pin ATX +12 Volt power cable, for one)

Perhaps there is an unused computer that has a Power Supply you can borrow.
Maybe someone has upgraded to a better computer, and has an unused one with a compatible power supply for a test unit.

Building desktop: no beeps, no video The mobo LED are on, fan is running but getting no signal to monitor. I've tested the video card in another pc and confirmed working. The only time the mobo beeps...

If the cpu was bad- nothing would turn on--be sure the cable is good-- also be sure the VGA is enabled in the bios- since you cant see the video you have to reset the cmos setting--unplug the unit and remove the cmos battery-reinstall after one minute and check for video

My computer says no RGB signal what does that mean?

It essentially means No Video Signal.

You are not receiving a video signal TO the monitor.
The monitor seems to be working A-OK.

Problem may be,

1) Bad monitor cable.

If the monitor cable is removable from the monitor, suggest use a monitor cable that is known to be good for a test. Perhaps one from a working computer, just borrowed for a test.

If the monitor cable is of the type that is not removable, try another known to be good monitor with cable, if available.

2) If this problem is listed in the correct category, and the desktop computer is a Gateway GT5404,

The GT5404 comes stock with Integrated Graphics. This is a graphics chip that is soldered to the motherboard.
(Another name for Integrated Graphics is OnBoard graphics. On the motherBoard)

The graphics chip is an Intel GMA 950. {Intel Graphics Media Accelerator]

This GPU is soldered to the motherboard.

[Chip and Chipset are slang terms for I.C. Integrated Circuit.
GPU stands for Graphics Processing Unit.
A type of 'Chip', ]

If this GPU is at fault, you'll receive no video signal.

You can use a video (Graphics) card to bypass using the Integrated Graphics, and have your graphics back.

(Don't forget to plug the monitor cable into the graphics card, not to the motherboard. Don't laugh! {Lol!} I've guided people who have done this)

The GT5404's, Intel (Coryville) 945G motherboard has a PCI-Express x16 slot for a graphics card.

Supporting data:

Click on the heading - Specifications. Read down to the subheading - Add-in Card Slots.
One PCI Express x16 (graphics interface)
One PCI Express x1
Two PCI conventional.

Also go back to the main menu, and click on Components.
Scroll down to the subheading - Motherboards, and click on -
4006158R - Intel (Coryville) 945G Motherboard

[ Note* Uses the PCI Express 1.1 technology.
The Intel 945G chip came out May 2005. PCI Express 2.0 technology didn't come out until January 15, 2007.

You can still use a graphics card based on the PCI Express 2.0 technology.
PCI Express 2.0 technology is Backward Compatible, with PCI Express 1.1 technology.

You just won't get the full capabilities of the PCI Express 2.0 graphics card.
Will you notice?
Also a Pentium 4 processor is not a high gamer processor. Single Core processor. It is a 'bottleneck' for graphics information, when trying to play intense newer games ]

3) Largest problem/s directly related to a failed computer (About an 80 percent ratio, or higher)

Dirty Computer Inside/Bad Power Supply:

Dirty Computer
A large percentage of computer problems are directly related to the inside of the computer being dirty, as well as the inside of the power supply.
Using a can of air on a regular basis as needed, could have prevented this problem.

(Computer - Unplugged from power.
Open computer case, Touch the metal frame {Non-painted surface} to relieve your body of Static electricity, before beginning to clean)

The hardware components located inside a personal computer, are cooled by air.

Air is drawn in through the front of the computer case, drawn over the cooling components for the Processor, (Heatsink/Fan combo),
and out through an exhaust case fan at the back of the case, and/or, air is drawn out through the Power Supply.

If the finned Heatsink has the spaces between the fins clogged, and the Processor's fan is clogged, the cooling capacity will drop tremendously.

A Processor has a Thermal Limit. It can only get so hot, before it turns off. (BIOS turns it off)
No Processor running, no computer. No computer = No Video Signal on monitor.

Power Supply
When the cooling components for a Power Supply are clogged, (Heatsinks inside, and the fan, are a Power Supply's cooling components), the Power Supply heats up.

Heat = Wasted Energy
The Power Supply tries to keep up with the call for power, and eventually components inside the power supply break down, or fail.

This cause a weak voltage power rail.
1) ALL the lights use less than 1 Watt of power
2) EACH fan uses 2 to 3 Watts
3) A typical Processor uses 51 to 125 Watts at maximum capability. Depends on what Processor it is.

Your power supply could still deliver enough voltage to light lamps, and even spin fans, but not enough for the Processor.

I would substitute the monitor cable first. Then (Computer unplugged from power), I would open the computer case, and see how dirty it is inside, and the Power Supply.

If you wish to know how to test your Power Supply, simply state so in a Comment. (Believe upper right of page)
You'll need an inexpensive multimeter (About $10 -$12), or a power supply tester.

Intel D945GCZ, PCI-E video card

Mostly PCI-E now are good vga card, i have a tip for you... there's is a secret between a 512MB & 1GB PCI-E card. With this feature is required a good power supply, like for example I used Power Supply 550watts (original 500watts power supply). This power supply is different from 350watts and 500watts.. Here is a secret buy a 550 watts to boost PCI-E card both 512MB & 1GB. Secretly this performance are based on my own analysis using CPU booster freeware... I'm sure 100% more compatible & perfectly to your motherboard. Just try it at least you have idea where you want to grab PCI-E cards (any Model).
Good luck!
