Question about ATI RADEON HD 2400 PRO Graphic Card

1 Answer

No video I bought a new graphics card, put it in and i get no input on my monitor. The installation guide said I might need more power to it. How do I do that. I have HP Pavilion a450n. I don't see where to put the cable in the power box to connect the graphics card.

    I also put a new video card in my computer recently. I purchased an ATI RADEON HD 2400 PRO with a universal PCI Bus Type. I believe my computer meets all of the system requirements. Anyhow, whenever I boot up my computer with the new video card, the monitor remains black. I uninstalled all of the drivers for my previous video card and followed the instruction/installation manual precisely. There was no space on the videocard to plug in an additional power supply, either, so I'm guessing the card I purchased doesn't require one. I really can not figure out what is causing my monitor to have no display (black screen, sometimes even stays in standby mode [orange light instead of green]).

What videocard did you buy? You cannot add external power to it. You may have to change the Power supply unit. Check the capacity of the supply. It is recommended to have at least 700 watts of power with the new video card theses days.

How do i find out witch display driver to disable so i can install new video card

You don't need to disable any driver, unplug, use ESD protection, install Graphics Card, move the monitor cable to the new card,(you may have to boot on the old monitor connection and install driver), install the driver for the new card and reboot plug into the new card. Do your windows updates to obtain the latest driver. You can open the Device Manager, open Display adapters and disable the Intel graphics adapter. Is it a PCI or AGP Graphics Card? Remember: with a Aftermarket Graphics Card it requires more Power/Watts, you should consider a PSU upgrade. You didn't post the Make, Model Graphics Card, usually there is a Min. Power Spec. for the card listed on the box.

When the monitor is turned on it appears to work - the "acer" name comes up and then the words "no signal". As soon as no signal comes on the sceen it goes to black and the light turns...

You might have one of several problems.

Your monitor might require a driver for your computer/graphics card in order to show up.
Your monitor's input might be slightly damaged.
Or your graphics card might not have the proper drivers in order to display on that kind of monitor.

I would go online and make sure your drivers are up to date for your graphics card first, then inspect your monitor to make sure no pins from the cable have broken into the input, and then make sure that your monitor is compatible with/without drivers to your graphics card.

I bought Foxconn 755A01-6EKRS Motherboard for my HP pc replacement. i install my AGP VsionTek x1300 graphic card and turn it on and nothing show up on screen...then i put the graphic card back to my old HP...

Your new Foxconn motherboard Primary Graphics Adapter settings in set to onboard vga that is why there is no display in your monitor. Do not install yet your agp video card. Use first the onboard vga of the motherboard.
Power up your computer and go to the BIOS settings. Locate in bios about the Primary Graphics Adapter settings and then select AGP. Save changes and the exit. Turn off your computer and now install the agp video card.

When you power up and no video made sure that you monitor cord plug directly to your video card not on the motherboard.

Usually if you have new installed video card the on-board video was automatically disabled. So check your monitor cord and plug it to the new installed video card.

Installing a new pci-e video

For one, what you can do is put in your old card. Install the NEW drivers for your 9500GT and shutdown. Install new Graphics card. (I would double check for an "ATX" power input on the card.)(, im sure it needs one) and that should hopefully help, Also consult your motherboard booklet and your graphics card booklet to see if the card is compatible. Hope this helps!

The Monitor Does Not Open Using My New Video Card

That is clear indication that you have a bad graphics card. Try to look for a pencil eraser and use it to clean the gold pins on your graphics card. I hope this helps. If your card still doesn't work, its probably defective.

I can't get monitor to come on even though the power light is on

Since it's a new card and you know it's working, install it last. Take it out for now and use the integrated video. Start the computer, enter the BIOS setup and disable the integrated video. Save the new settings and shut off the computer. Then put in the new video card and restart.

Motherboard graphics card not working, trying to install MicroStar G4MX420D nividia

Can you get into the BIOS setup? Usually, it will say "For Setup Press Fn" when you start booting up. When you get into the setup, look for a menu item that deals with "onboard video". Set it to disable. Then "Save and Exit" the BIOS. The new video board should allow you to view the screen, at a reduced resolution, until you load the new software.

Radeon X1650


before doing anything.. What do you mean you get no blank monitor? Do you see anything at all? Do you see the POST running? Also, when you put in the AGP, did you plug your monitor into the new card? Or are you trying to boot from the old intergrated one?

You can change your graphics input in the BIOS from integrated to AGP (after putting in the new card). But, It should pick it up fine without changing it. And if it doesn't work after doing so, your motherboard may keep the settings, and then a deeper problem arises..

Tried To Install New Card, monitor not responding.

Tech is suggesting that you pressed too hard while switching back & forth & may have hurt the motherboard by bending it. This a common problem. I can only suggest that remove your old card & clean the PCI slot with canned air. Carefully reseat the old card pressing evenly downwards till the card is seated. Use a flashlight & check where the card connects to the slot. It should be level across the PCI slot. Do this while the power cord is unpluged from the PC. Plug the power back in & start the PC.
Some video cards require extra power. Your newer card may need a four pin power connector to run. Please check the instructions that came with the RADEON X1300.
