New graphics card assistance?

Question

Hello and thank you first, for your consideration concerning my problem.

Today I just installed a new graphics card (Geforce GTX 460), but have had no success in getting it working. I believe I followed the correct procedure in setting it up, properly putting it into the motherboard and powering it with two"six-pin" adapters, yet for some reason when I plug the adapter from my monitor into the new card, the screen remains black. One problem I've faced, that I suspect might be causing it, is that I was unable to remove the old card (was screwed in precariously. Radeon HD 4350) from the motherboard, and now have the two in at the same time. Is it possible that the original card is conflicting with the new one and how do I step around this?

The new card is definitely being powered, as I can hear the fans whirring away, yet for some reason it does not show up under "display adapters" in the device manager. I know the card is compatible with my motherboard. I have also yet to touch any computer setting as I worry that I will not be able to revert back, in case the graphics card proves a no-go.

The above, summarized in a more easy to read format:
- I have just installed a new card, an Nvidia Geforce GTX 460
- I believe I have followed all procedure correctly, including the six pins and the card is receiving power as I can hear the fans whirring. I only failed one step in the procedure...
- The one step I failed was removing the original graphics card, which was screwed in behind the motherboard and would require the removal of the motherboard to accomplish. Thus, I have two cards currently in the motherboard.
- When I plug my monitor into the new card, the screen will remain blank. However, when I plug my monitor into the old card, the screen works.
- The new card is not showing up in the "display adapters" underneath device manager either - even after scanning for new hardware.
- Have not attempted installing the drivers for the new cards. I feared it might harm my old cards drivers if I tried.

Q. Are my two cards conflicting?
Q. What is the most likely problem and how do I resolve this?
Q. Can you please give me a rundown of the settings I'll need to fix/alter, and whether or not they are revertible in case of cataclysm?

Please help me. I have tried to do all of this as a present for my younger brother, who has just made the national swim team.

Much appreciated. William.

Answer 1

I'd have to ask what you meant by screwed in behind the motherboard. It's either in a PCI slot or it isn't. If it isn't, it's integrated graphics (a vga port ON the mobo) and you might boot to the bios and disable it in the video settings. It would help considerably if you posted the pc make and model.

Edit: The bios version tells us nothing. We NEED the motherboard make and model.

Answer 2

I am no longer certain what will match to your laptop, I suppose you can investigate this though from the link. Whether it is AGP, i'd strongly endorse a brand new pc, a video card would now not be valued at shopping. If it is PCI-specific, you're in luck. I would not get a 9800gt, get at least a nvidia 250 gts. Get some thing equal to or above an nvidia 250 and 450, and ati 4500 or 5500. Determine the second hyperlink to get an suggestion how they rank amongst every other. Final, i might buy new. You don't know the condition a video card is in, video playing cards exit like light bulbs.

Answer 3

I would say the same as DrDave. When you boot your PC up go into your BIOS settings and somewhere you will find a section on what graphics card it will boot up i.e. "onboard" or "AGP" or even PCI or newer PCI-E now depending on your Motherboard it may even give you the option to load both cards Like SLI as some AMD board have this function where it will use both onboard and external graphics card but the fact that you can still start the system using the old card shows me you just need to tell the BIOS to boot the new external graphics card not the old one.



Hope this helps :)

Answer 4

its easy. you bought a new video card.

take the Radeon HD 4350 out any way possible...

and then you put in the GTX 460.



if you have both of them in at the same time.. the computer is only going to run on the HD 4350 b/c its plugged into slot 1.





slot 1.. is the highest pci-E slot in the computer case.
