I hope someone can help me. I just purchased a new graphics card and some ram so I can play a game online. I followed all the instructions but my pc will not recognize my new card. The new card I have is a geforce 9400 gt pci-e 2.0.I have a integrated graphics card so I disabled it before I installed the card and nothing. I tried enabling the onboard card than installing and nothing. I went in bios and enabled the pcie express slot and nothing. Well the pc wont recognize the card so that would be no good. Then I uninstalled the integrated card and still nothing. I installed the ram with no hassles. Could it possibly be my pc power supply? The power supply is 300watts and the graphics card requires 300watts. I made sure I at least got one to much with my pc. I don't want to buy a power supply unit right now cause that might not be the cause. My pc is not that old its a hp a1600n http://h10025.www1.hp.com/ewfrf/wc/documen...product=3245022 Does anyone have any clue what could be wrong? Thanks

Are you sure the card was seated firmly in place? Did you take it out and reinsert it?
Did you install or attempt to install the drivers?

theres more to it then wattage, amperage is also important. How much amps are on the 12v rails of your power supply? also, just to check a lot of people do this, does the video card require a PCI_E power cable running directly from the PSU? if so, if you dont have that hooked up your video card will not turn on. and explain what its doing. when you install it, will the computer turn on? go to bios, the OS, exactly what does it do. what do you mean by it wont recognize the card? is there no display when you turn it on, or does it only use standard VGA adaptors and boot into windows at a low resolution and say you have a unrecognized device?

So here's the checklist:

1. Have you checked the card on another system?
2. A 9400 GT requires alteast 18A on the +12V rail of your PSU.
3. Make sure it is firmly in place, in the PCI Express x16 slot.
4. Make sure the DVI/VGA cable works and is well in place.
5. After you have installed the card, you need to enter the BIOS and enable the PCI-E card.

A decent PSU from Seasonic or Corsair would be a worthwhile investment. :thumbsup:

Well I checked out everything you guys said except I don't have another system to test it on. My psu has 18A and 12V. The graphics card is installed firmly. My VGA cord works fine. Ok this time I uninstalled the onboard graphics. I reinstalled the new graphics card. Made sure it was firmly in place. Left the pc cover off so I can see if it was getting power and yes the fan works. When the pc was starting I entered bios and enabled the pcie express slot. When I did that I did not get a signal from the monitor only a black screen. I'm using a VGA cable. I plugged the cable back into the original port and still no signal. I did receive audio. So I guess when I enable the pcie slot there is no video signal. When I took the new graphics card out I got a video signal. Forgot to add when I tried to install the video drivers from the cd it just says runtime error. It also says that when the new graphics card is not installed. The card is not located in device drivers either. This is frustrating. Thank you guys for your help.

I also forgot to add I dont know what you call them but there is a small white plugin on top of the graphics card. It looks like the rest of the plugins in the pc just small and white. The graphics card did not come with any extra cables nor did it say anything about attaching a cable into the card in the instructions.

Which card is this? Link to the exact model please?
And you are sure the fan was spinning, when you inserted it into the PCIe slot?

Yes I'm sure the fan was spinning. I checked multiple times. Its a Geforce 9400 Gt PCI-E 2.0 Here is the link http://www.keenzo.com/showproduct.asp?ID=3753573 I know I have a 1.0 or 1.1 mobo but I read 2.0 was backward compatible.

so it does get into windows? if you try to install the driver to a card that is not there, then chances are it may give you errors including runtime errors. IF the card is not putting out any signal (even to get to BIOS) then chances are you have a bad card, or the video card is not getting enough power (if your sure you installed everything right) for some reason. One thing you might check is how much power the PCI express lane is set to supply to the video card, and I can't find it, but ill keep looking, how much power the card needs.

The requirements were 300watts 18A 12V. My psu has these numbers exactly. The thing is I don't think its a bad card because I searched and a lot of people are having this issue especially people that have hp computers and Integrated graphics card. I don't know I tried everything. I might just reinstall windows and see if anything happens. I don't have anything important on my pc. Well thanks again if you think of anything let me know.

well keep in mind those are minimum requirements, its always good to have a PSU rated higher, though I don't think that is your problem. I was refering more about the power coming from the motherboard. See, with that card it draws its power from the motherboard which gets it from the PSU. the motherboard distributes the power to the individual components. Typically, you can tell what voltage the PCI express lane is giving to the video card in the BIOS. I would check that. Also, it is possibly the PCI E lane does not work. do you have any other PCI express cards you can test it with? it doesnt have to be a PCI express 16 card, any pcie express card will work (PCI express x1 x4 and x8 cards will work in a x16 slot) if you cant get them to work in the slot, then chances are the slot is defective.

Like the_patriot09 pointed out, just meeting the specifications isn't advisable.

The card's MINIMUM requirement is a 300W PSU, which of course has to power other components in your PC. So a little extra room is always good.

Now this may or may not be the problem here.

Assuming you have got the connections right and enabled the PCIe card as the primary video adapter in the BIOS , the card could be at fault or maybe the PCIe slot doesn't work.

The only way you'll know is if you try it on another PC somehow or maybe try a different card on your PC.

Sooner you do that, the sooner you get a replacement card.

Hey well after countless tries to get it working I failed. I just had a question though. It probably is the power supply so I ordered a unit. I also ordered a cheaper graphics card so I can see if there is something wrong with the slot. I only had $30 to spare on a psu. I purchased a 400watt. My current psu is 300. Do you think that will be a large enough increase to get the card to start working since the graphics card minimum is 300watts? Here's the link to the psu I purchased http://www.geeks.com/details.asp?invtid=14616-DT&cat=PWR

Well, you could have purchased something with higher AMPs on the +12v rail.

Anyway, looks like the Coolmax V-400 has two +12V rails:
+12V1 -18A
+12V2 -16A

Use the first one.
