No display with external graphic card

Asked By iamainul 0 points N/A Posted on - 08/28/2011

Hi,

I am using intel core i3 with intel DH55HC motherboard. Recently i bought xfx ati 5670 agp with 1gb ddr5 memory. After two months  i have no display but there is no beep tone which is naturally occur when hardware errors. So i connect my monitor with the build in agp slot with my motherboard and i have display. But when ever i connect with my external agp i have the same problem. I pull out my agp and find out some rust on it. Is the rust which is causing the problem or it my apg which is gone of ever?

Let me add some thing that i had similar problem before purchasing the xfx agp. Then i was using MSI NVIDIA 240 1gb ddr5 agp. Is the agp or my motherboard is causing problem?

No display with external graphic card

Hi,

Intel core i3 motherboard/cpus have very good video card already, if you are not using very high graphic heavy games, then i3 integrated VGA is already great. So you were able to use the external video card right and did not work after 2 months? Try these solutions i have:

a. Clean your cable ports, make sure no rust. you can buy those rust cleaning sprays or PC cleaner.

b. Make sure you install the external(dedicated) graphic card driver properly. This will manage your video display, which output to use.

c. Try known good cables that connect notebook to monitor, or test your agp card with another computer.

d. if everything above is okay and problem still persists, it should be with your computer display settings. Just make sure you set it up properly. Go to your control panel and display> screen resolution and detect the output of your display. it should show you options.

No display with external graphic card

Whenever you have problems with your display, the very first you should check is the video display plug that is connecting your monitor to your CPU. It might just get a little lose. If you find its ok and the plug is secured then check the inside of your CPU. If you are using multiple video cards, then most likely this would really happen.

Go check the video card inside your CPU. Remove it from the slot. Clean the PCI slot or the AGP slot to which your video card is attached. Use a brush to remove the dirt inside the slot. Much better if you could do a big blow on the slot with your mouth to expel the dust accumulating inside. Also check the card itself. Usually, the copper part of any other card devices attached to any slots gets too dusty that the dirt already stick on the copper as if it was a mold. Clean the copper part with an eraser. Don’t use any liquid or fluid. An ordinary pencil eraser will do. Rub the copper part with the eraser on both sides. Wipe it with a clean cloth then attach it again to the slot. Reboot your computer.

If you use your computer mostly on gaming, just stick to one video card and avoid using multiple video cards on your computer so you won’t get problems like this.

That “rust” you see in the contact pins of the video card is actually not a rust but the accumulation of dirt. This is common to electronic components. If your display works whenever you connect your monitor to the built-in video card of motherboard but not with your dedicated video card, you should remove the video card from the slot and check the contact pins if they are dirty.

Cleaning the pins is pretty simple. Just get a pencil eraser and rub it to the gold-colored contact pins of the video card. Do it on both sides. When you are finished, wipe it with a dry clean cloth and then replace it in the slot. Try connecting your monitor again to the dedicated video card and see if it works.

If it doesn’t work on one slot, try transferring the video card to another slot and try again.
