Question about ASUS EAX1800XT/2DHTV RADEON X1800 XT, (512 MB) PCI Express Graphic Card

1 Answer

It doesn't boot up/work/register

When i plug my card into the pci-e slot, and switch the computer on, a small red light near the pci-e extra power port lights up with the label T_FAULT and i have no idea what that means. other than that, plugging the monitor into the card shows nothing, and in windows it does not register

    I have the 6 pin converted power connector. it's plugged in. (e.g. if its unplugged it registers on the card, as the ext_pwr LED will then also light up.)

    Currently it doesn't.. all i can see is that the fan switches on (...the thing sounds like a mini jet taking off) and the T_FAULT LED lights up.

    Having in effect disabled the on-board Intel GMA graphics via the BIOS, and switching to external PCI-E card output, i know that if i plug the monitor into the card it should show up on screen, (my old, tired 7900GT still works so the slot is fine and the power works.) but it doesn't, the mobo then reverts to the on-board and boots windows. Though windows doesn't even register that the card's been plugged in.

    I checked the seating and its fine, replaced it a few times too. I have an LPG6-500W power supply and since i have but a modest student budget i haven't yet opted for a stronger system, so I'm hoping its not a new power supply fix yet. The card is second hand and was given to me free... it should work, but i can get it to work.

    I've downloaded the user's manual and checked it but couldn't find a good reference in troubleshooting, and the internet is littered with complaints about the card and the T_FAULT thing but no one seems to know what its indicating and most fixes were things like BIOS upgrades (check), miraculous workings (nope), or taking out the RAM and replacing (check)

The x1800 is a high-end video card, and requires you to plug a power connector into the back of the card. If this is not installed, the video card will not work.

The card should have come with an adapter to change the standard hard-drive style 4 pin molex power connector into the 6 or 8 pin adapter for the video card.

Optiplex 740 Computer Won't Start

1. Verify it is plugged in.
2. Press power button.
- does your power supply have a switch on it? Look for a black rocker switch
3. Do you hear a beep?
4. If you hear a loud continuos beep, power down the Machine and unplug it.
5. Hold power button while PC is off, it may come on for a second.. This is called "bleeding the capacitors"
6. Open the side of the case.
7. Find the RAM (random access memory), they are long rectangles about 6inches by 1inch. Remove one.
8. Plug in power cable and start computer with one stick of RAM, problem solved, you have bad ram.
9. Remove all PCI cards, and cards that are in the back of the computer. Remove them from the white slots, there is a small screw on the side near the back of the computer to unscrew, you will need to remove a small black door that holds the cards in place. BE SURE power cable is unplugged.
10. Power the computer on. If your computer turns on, you win.
Power down Machine and add cards until it doesn't work, the card you insert and causes the computer to not boot is the card that is shorting out.
11. When you plug in the computer are there any lights on the mother board. If so at least your power supply is working.
12. No light? You need a new power supply. There are 4 screws on the outside of the case where you were plugging and Un plugging the power cable. Remove screws and remove power supply, you will need to disconnect all connections. Type any and all numbers into an Amazon search and spend the $25, Amazon is safe.
13. If you are "posting" entering the BIOS (basic input output system) you're not in bad shape. This means your power supply is working and rh motherboard is working.
14. Restart computer and keep pressing f2, arrow over to advanced, then down to "boot options" make sure your hard drive is on top of the list" if it is not, move it there.
15. press F10 to exit and save changes.

My ATI firepro V7800 makes continuous beeping noise. PC does not boot when I turn it on.....pls help!!!

1) Believe the continuous beeping you hear is a BIOS Beep Code, stating you have a graphics problem. Computer, not video card, is beeping.

2) Do you have the external 6-pin PCI-Express power cable plugged into the graphics card, from the Power Supply?

3) IF, your Power Supply does not have a 6-pin PCI-Express power cable, are you using TWO 4-pin Peripheral power cables, connected to a 6-pin PCI-Express adapter power cable?

To wit;

6-pin PCI-Express power cable example, and also showing a 6-pin PCI-Express adapter power cable on the right,

Example of a 4-pin Peripheral power cable,
(Misnomered by many as a 'Molex' power cable. Molex was the first company to make that type of connector. The name stuck, kind of like calling an adjustable open-end wrench a Crescent wrench),

Note the color code of the wires used in a 4-pin Peripheral power cable, and a 6-pin PCI-Express power cable.

Red = 5 Volt wire
Yellow = 12 Volt wire
(All are DC Voltage)
Black = Ground wire. (ALL Black wires are Ground wires)

The 4-pin Peripheral power cable has ONE Yellow 12 Volt wire.
The 6-pin PCI-Express power cable has TWO Yellow 12 Volt wires.

The most power that a PCI-Express x16 expansion slot can deliver, is 75 Watts.

"This cable is used to provide extra 12 volt power to PCI Express expansion cards. PCI Express motherboard slots can provide a maximum of 75 watts."

"The older 6 pin version officially provides a maximum of 75 watts (although unofficially it can usually provide much more)"

The ATI FirePro V7800 graphics card requires 150 Watts by itself.

The PCI-Express x16 expansion slot CANNOT deliver the recommended power (Wattage) needed, therefore an external power cable capable of delivering 75 Watts is needed.

What happens if you just use ONE 4-pin Peripheral power cable, in a 6-pin PCI-Express adapter power cable?

The PCI-Express x16 expansion slot contact pins -> BURN

The gold plated contact pins on the bottom of the graphics card -

The connection on the graphics card for the 6-pin PCI-Express power cable - BURNS

The contact pins in the 6-pin PCI-Express adapter power cable -

If it is too bad, and cannot be remedied by cleaning, the motherboard is TOAST, and so is the graphics card.

For additional questions please post in a Comment.

How to add usb ports to Dell 530

Suggest use a USB adapter card.

More specifically a PCI USB adapter card.

Dell Support > Inspiron 530 Series Desktop PC > Owner's Manual,

In the list click on - Removing and Installing parts

1) Unplug the computer from power.
[Unplug FROM the surge protector, not the back of the computer. (Power Supply)
Unplugging from the back could lead to a power surge ]

2) Computer on a table open the computer case,
Click on - Removing the Computer Cover - in the list.

3) FOLLOW Anti-Static Precautions
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware inside the 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.

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


Here you see an illustration of your motherboard. Oriented as it is in your computer case. (Just no hardware components, nor cables are attached)

At the bottom of the motherboard are 2 White long expansion slots.
In the illustration they are labeled by the numbers 21 and 22.
If one of these slots is open, and not being used, you can install a PCI USB adapter card.

This is one example of a PCI USB adapter card,

At the back of the computer, located towards the bottom, are the Expansion Slots.
Four horizontal slots.

If there isn't some sort of add-on adapter card already installed, all of the expansion slots will be covered with an Expansion Slot Cover.

If there is an add-on adapter card installed of course, one of the expansion slot covers will be removed.

Line up the PCI USB adapter card with the open PCI slot, you have chosen.
Now look at the expansion slots at the rear of the computer.
Notice what expansion slot that the PCI USB card's bracket, lines up with.

Go to the back of the computer, and view the small metal bracket on the bottom right. Loosen the Thumbscrew, and swing the bracket out. (Thumbscrew is supposed to just loosen, not come out)

Remove the expansion slot cover for your PCI slot choice.
Install the PCI USB adapter card.
Note that there is a Locating Lug in the PCI slot, and a matching Locating Notch, on the PCI USB adapter card.

Line them up, then push the PCI USB card straight down into the PCI slot.
Also watch the metal bracket on the back of the PCI USB card.
The 'tang' at the Bottom, slides down in-between the framework.

The top of the bracket has a half-moon notch, that lines up with a small 'dowel' on the computer case framework.
Make sure it is aligned, and the bracket is aligned.

What I am referring to will become readily apparent, as you go to install the PCI USB card.
If there are any other add-on adapter cards, they may try to fall out, when you go to install the new add-on card.

You just have to line them up, so their bracket notches are all on the 'dowels', and hold them in place. Then swing the 'door' closed. Tighten the thumbscrew.

If you have an Add-on card in the way, and by moving it to the other PCI slot, will allow you to install the PCI USB card, go ahead, and move it.
Doesn't matter. BIOS will find it, and assign an Interrupt Request.

There are two other expansion slots above the 2 white PCI slots.
The expansion slot right above the top PCI slot, is a PCI-Express x1 slot.
If this slot is open, OR the only one available, you can use a PCI-Express USB adapter card.


The last expansion slot you have is above the PCI-Express x1 slot.
This is a PCI-Express x16 slot, and is ONLY used for a graphics card.

Just installed mobo ms-7091 m atx but find it as no video out ports how do i get a picture.i know its old but its my first attempt at building pc can i just install a graphics card.

I found the user manual here :
Your motherboard provides 1 pci-express x16 slot, so you will need to install a pci-express video card.
Try to get a video card that doesn't need to be powered by the power supply. There are some out there that don't need to be powered, but .....
Most, but not all, pci-e video cards need to be plugged into your main computer power supply to work. If your power supply was designed to power a pci-e video card, it will have a 6 pin pci-e power connector to connect to a pci-e video card. If your power supply doesn't have this connector, you should replace the power supply with one with the pci-e power connector.

I have 945gcr mother board i bough one graphice card for my pc but its not working i have faceing some issue with my graphic card (nvidia 9500 gt) the probleme is whene i was insert card in to board then...

Try and do the following:
Have a look at the back of your graphics card there might be a 6 pin plug it provides extra power to the graphics card which will need to be plugged in before your PC will boot. If not try and get hold of another graphics card and insert that into your PC. Switch on the PC and see if you get a display. If the PC still does not want to boot up then the pci-express slot on your motherboard might be faulty. If it boots up then your graphics card might be faulty.

I have an old emachine it has a regular phone connection and i want to update it to ethernet connection can you help me?

This is a PCI Network Card. It plugs into a PCI expansion slot on your computer. You will need to install the drivers for this network card to work properly.

How to install a network card Some newer computers come with network interfaces built in - your machine carefully for a socket that looks like a large telephone socket with a network_symbol.jpg next to it. These are sometimes hidden behind a flap or on the corner of your laptop next to the modem socket.
If you haven't got a network interface already on your machine you will have to install a network interface card. These are available to buy from the IT Service Desk.
  • USB Adaptors simply plug into a USB port.
  • PCMCIA Cards for laptops slot in a free PCMCIA slot on the side of your machine.
  • PCI Cards are a bit more fiddly and require you to open up your machine.
  • We advise that you use a USB adaptor for ease of installation
Instructions on how to fit a PCI network interface card.
  1. Shut down Windows and then turn the computer off and unplug it. Never work in your computer's insides with the power on or the power cord plugged in!
  2. Remove the cover from your computer. There are normally a number of screws on the outside of the case to remove. Put the screws someplace where they won't wander off.
  3. Find an unused expansion slot inside the computer. The expansion slots are lined up in a neat row near the back of the computer. All new computers have at least three or four slots known as PCI slots.
  4. Many older computers also have several slots known as ISA slots. You can distinguish ISA slots from PCI slots by noting the size of the slots. PCI slots are smaller than ISA slots, so you can't accidentally insert a PCI card in an ISA slot or vice versa. Figure 2 shows the different types of slots. PCI slots are white, ISA slots are black
  5. When you find the right type of slot that doesn't have a card in it, remove the metal backplate from the back of the computer's chassis. A small retaining screw holds the backplate in place. Remove the screw, pull the backplate out, keep it in a safe place in case you ever want to remove the network card.
  6. Insert the network card into the slot. Line up the connectors on the bottom of the card with the connectors in the expansion slot, and then press the card straight down. Sometimes you have to press uncomfortably hard to get the card to slide into the slot.
  7. Ignored the little cable that came with the card, you can chuck this in the bin. It is a Wake-On-LAN connector and isn't required for your card to work.
  8. Secure the network card with the screw that you removed in Step 4.
  9. Put the computer's case back together. Watch out for the loose cables inside the computer; you don't want to pinch them with the case as you slide it back on. Secure the case with the screws that you removed in Step 2.
  10. Turn the computer back on.

Wirring for my mother board

The board may have tiny words printed on it telling you what the plugs are.

Most newer boards are fool proof in that only the specified cables can be plugged in. generally the Hard drive plugs into IDE 1 or MAIN and CD drives plug into IDE 2
Video cards go into the First slot usually. It may be AGP or PCI or PCI express depending on the board. The extra PCI slots are for extra devices like NIC cards and Sound card. Power cables cant be plugged in wrong because there male to female and only fit into there designed plugs.

Make sure the motherboard is installed correctly and is not touching the actaul case but held up with spacers. you can find these at most Computer stores.

Really try and find the manual online if you can. It may be necesary when plugging in the little pins for the power switch and USB pins.

good luck.

Wireless phone extension not working on receiver. Red light and horrible sound hen connection is attempted

You need to register the unit it will work:
Make sure the Base Unit is switched on and has a Green light showing.
2. Unplug everything connected to the Base Unit sockets (you will reconnect them later).
3. Plug the Extension Unit into a power point near the Base Unit, switch on the power and watch the light on the Extension Unit.
4. If the light on the Extension Unit is not glowing a steady Red then the Extension Unit must first be deregistered. Follow Step A and Step B in
the Deregistering an Extension Unit box below then try to register the Extension Unit again.
5. Plug one end of a supplied line cord into to either socket on the Base Unit and plug the other end into the extra Extension Unit
(This cord is used to do the actual registering).
6. The light on the Extension Unit will glow Red for up to a minute and then change to Green or Yellow.
7. Once you have the Green or Yellow light on the Extension Unit, unplug the line cord between the Base Unit and the Extension Unit
(You can unplug the Extension Unit – it will remember being registered).
8. Plug in everything that used to be connected to the Base Unit sockets.
9. Install the extra Extension Unit as per the Extension Unit Installation steps on the other side of this page.
