I bought a EVGA 9400 GT 1 GB video card. I have installed the updated drivers as well as the Control Panel software. When I start my computer
I receive an alert "PCi Express card is in 1x mode. Press F2 to go to
set up or F1 to continue". I go to set up But I donot know what I'm
supposed to do. The 9400 GT was resommended by Dell saying it's
compatible with my 8400. I get video to work but some of the videos the
sound is off by a scond or two. Any suggestions would be greatly

Re: EVGA 9400 GTvideo card problem only 1x mode
Sounds like the processor is not enough GHz to run the video card. If I am not mistaken the 9400 GT needs a 2.3GHz or higher processor and needs a 400 watt powersupply to run properly so if your computer is not set up to those specs the card will not work properly

It sounds like you have a corrupted Video Driver. Safe Mode uses defaulted video drivers that are in the operating system and are not specific to your video driver.
Boot into Safe Mode, go into Device Manager and UNINSTALL the video card from the PC (this is removing the info about the video card - DO NOT REMOVE the actual card from the PC).
Go to Control Panel and uninstall any video drivers or programs that are associated with your video card. There are two video card options for your Dell - an ATI and an Intel. If you see any ATI programs, go ahead and uninstall them as they may be corrupted as well.
Reboot the computer normally and it should boot correctly but with a very poor looking display. Go to the dell web site and download the drivers and install them. This step will likely require a reboot.
First of all you need to know what video card you have. If you have
Windows and I assume you do go to Start > Control Panel (switch to
classic view) > System click on Device Manager and in the list find
'Display Adapter'. The name of the driver appears. Make a note of it. Go
directly to the website of your driver's manufacturer. Follow the
instructions to download and install the right driver. Restart your
computer to let it take effect.
Warning: this is the manual way
to update. If you are not a tech guy, attempting to change video drivers
could make your computer inoperable or cause severe problems. As a
result, you can rely on a drive detective software to update the
driver issue automatically & accurately. This way also saves you
time & energy.
You just need to download the appropriate audio driver for your computer. Go to the Device Manager and install all missing drivers for "Unknown Devices". Either connect to the internet or use the driver disc which came with the motherboard of the computer.
For those who doesn't know how to access Device Manager, please follow the steps below.
For Windows XP:
Start -> Run -> Type devmgmt.msc (in the box) -> Right click Unknown device -> Properties -> Driver tab -> Update driver
For Windows Vista and Windows 7
Start -> Type devmgmt.msc (in the start search box) -> Right click Unknown device -> Properties -> Driver tab -> Update driver
Go to the HP website, choose your type of operation system, download the audio drivers and install:
If some drivers are still missing you can check them by looking inside the Device Manager: press WinKey+Pause > Hardware tab > Device manager
If you still experience problems, follow these steps:
1) If you have an original CD of your computer, motherboard, or audio card, insert the CD and install the driver from it. 2) Or alternatively insert the CD and go to: Start > Settings > Control Panel > Performance and Maintenance > System > Hardware > Device Manager, find any unidentified device in the list, or expand the "Sound, video and game controllers" branch, identify the Audio card > Right click > Update driver... > Install the software automatically > Next 3) Or alternatively download and install a free driver updater software, e.g. http://www.innovative-sol.com/drivermax/index.htm - let it scan and update all your missing drivers. P.S. These steps mentioned above are for Windows XP, but will be quite similar on other Windows versions, too.
Remove the GeForce card.
Enable the onboard video as "primary".
Within Device Manager, remove the driver for the GeForce adapter.
Download the latest software software for the GeForce video-card,
and install it.
Insert the GeForce card, and leave the onboard video as "Primary".
It should treat the GeForce card as an "additional" video-adapter,
as if you had two monitors, side-by-side.
If it works in this configuration, shutdown.
Set the GeForce card to "primary" and restart.
If it works in this configuration, shutdown.
Set the onboard video to "disabled".
you really didn't need a new psu for that videocard, but it can either be a burned videocard or the monitor can't support the refresh rate the videocard is outputting. although, the card really should default to its lowest setting upon installing in a new system, try connecting another monitor. if you get a screen, thats good, if not, try booting into safe mode holding f8 right before the windows loading screen appears.
