Question about XFX GeForce 6800 GT, (256 MB) Graphic Card

1 Answer

New graphics card, no picture

Just bought the Sparkle GeForce 8400gs 512mb PCI graphics card, and a new power supply to run it. The system starts fine until windows is suppose to open on the monitor. It just stays black. It shows me all the pre-windows start-up stuff, and keeps running afterwards. I just can't see what's going on. The computer is a Dell Optiplex gx280 running win xp.

    I reduced the resolution in both VGA mode and Safe mode, and neither one worked. Although, Safe mode did allow me to install the driver for it, even that did not help.

    Basicly the same issue. I have a PNY GeForce 8400 PCI 512 DDR that I just purchaced as well as a new power supply to support it. Prior to installing the drivers it booted up fine. I then installed the drivers and apon reboot I just get a black screen.

    You can see the whole boot process, windows XP loading, but you never get to the login screen. Monitor still shows that its getting signal but everything is black.

    I can login to safe mode fine and that works. Tried changing resolution but did nothing. Also tested with a new monitor that I have with my newest PC and it was not showing a thing either. Does not seem to be a monitor issue.

    Any other ideas

My minecraft crashed!


There can be many reasons that Minecraft can crash. I need more details. Did you get any error messages? Some things you might try: Update Java, update your launcher (free at minecraft.net if you already bought it). Also, your graphics card has a really low amount of RAM, make sure you have the newest drivers for it or just replace it.

About geforce 8400gs gen2 tc1g 64bit ddr2, it is okey to run in window7 32bit. i already install and run but only read 512mb.


There should be no reason why this card won't work with Windows 7 32bit, it could be as simple as your Graphics drivers are out of date. I recommend downloading the latest Windows 7 drivers for your card at the Nvidia website.

Just remember graphics RAM and SDRAM are two completely different things so they don't add up.
As far as I know the 8400GS is a 256MB card.

Black Screen after installing new NVidia 9400GT


Put the old card back in, remove the old drivers and restart it in VGA mode.
You don't say what operating system you use, but XP & Vista you should be able to hit F8 before the windows splash screen to select VGA mode or Safe Mode.
Once you do that you should be able to put the new card in and start it in standard VGA mode then load the new drivers.

Video card not installing


Did you make sure you uninstalled the original 9600gt driver, other than that you could try safe mode with networking and download/install the driver.
