ASUS EN7950 GT 512MB .. pROBLEM!

Hi. My computer is Dell 8400 Dimension, windows XP. bought about a year and a half ago I bought a new card, ASUS EN7950 GT 512MB and tried to install it. I deleted my old VGA driver, (x300) and turned the computer off, plugged the new 7950gt (with auxilary power cables plugged), and turned my computer on. The moment when my computer was on, the monitor got pixilated, with green stripes and purple stripes. most of all, It WOULDN'T GO PAST THE xp loading bar. strange Changing green pattern appears and my computer goes blank, and that blue screen appears saying: something about nv4_disp how the device got stuck into an infinite loop and how the problem might be the hardware itself or the driver in charge of the hardware. I can't even get to setting up the drivers of 7950 cause it can't get to windows XP. I tried VGA and Safe mode, but it doesn't install there. I believe that somehow the drivers of my old ATI card isn't clearly deleted (but i deleted it using control panel and checked with device manager and it was gone) and was clashing with the new nvidia card.. Help please..

    by the way my computer's psu is crappy 350w...
    maybe this is the problem. But not too sure.

  • Problema Oct 10, 2007

    you mean i should install my x300 and 7950gt drivers at the same time, when my computer's running on x300, then boot up then load the asus drivers and close the system and install the 7950gt and boot up? and then delete the x300 drivers?


    is in't it the psus problem? I heard that 7950gt needs at least 400w of powersupply... but i will try your idea.

    thanks for the kind reply


  • Problema Oct 10, 2007

    i cannot install the drivers for 7950gt while i'm using x300. It says that it cannot find the correct hardware for the driver...(it should say that cause i'm using x300 at the time of installation..)

    so it doesn't work.

    or am i following your instructions unclearly.  . .

Your PSU isn't the problem.  350W is more then enough to run the video card into windows... Windows isn't 3d accelerated meaning the video card can run in it without the video card's power supply intact. Like Beni said, go into your Bios and disable your old WGA and activate Plug and Play as your main. Hope you get this fixed :D

Hi, I think you will need to run the Dell restore disk, install the orriginal drivers and use the dell system to bootup then load the drivers the ASUS drivers then close the system, install the new card and then bootup. on doing this there will be resident drivers for the new card and it should work fine, then delete the orriginal drivers.

No sound on my dell 8400

Simply go to 'Start -> Control Panel -> Administrative tools -> Computer management -> Device manager'. Now find here 'Sound, video and game controllers', right-click on your sound device and select 'Properties'.

Now click 'Driver' tab and check that what driver is currently installed and it is working properly or not...

Update the audio driver now still the device says it is working properly because sometime the driver might be causing this problem.

Don't forget to restart you laptop after successfully installed new driver.

My computer just stop to producing sound from speakers even the welcoming window xp sound,


The audio driver might have been corrupted. You just need to download the appropriate audio driver for your motherboard. 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 your motherboard.

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

Hope this helps.

I have a Dell Dimension 8400. The hard drive crashed so I went to the Dell website, entered my System Service Tag #, bought the reccomended "compatible" hard drive which is WD 1600AAJS 160 GB...

It will be easier if you will have it checked with any computer technician. They will normally charge a very minimal fee for this very common kind of problem.

Be sure to be there when he checked your computer, so he can also teach you about it.

My system says, (RAM) radon access memory low cpu intel (r) pentium 4 cpu, version 2.80 ghz. RAM 256 mb. What can I do to resolve this problem. Dell 4700 dimension

Windows XP requires a "bare-minimum" of 128MB of RAM, works "OK" with your 256MB of RAM, if you don't open too many programs at the same time, and if you close/re-open Internet Explorer about once an hour of usage.

But, Windows XP would be _much_ "happier" if you added 256MB or 512MB of RAM, because it is telling you ("available random access memory is low") that it is using all the RAM.

Add more RAM -- your computer will run much better.

NVIDA 8400

I don't know if you have tried this yet, but here goes......
When the PC first powers up, hit the F2 or delete key to enter the setup page. See if there is a spot where you can disable the onboard graphics, then save the settings, reboot the PC, and see if this helps the problem. And there is always the chance that the graphics card is no good. And nothing but a return, and a new card will solve the problem.

Card, Graphic, 128, X800, SE need to up grade the new high end

if you dont want to have to upgrade your power supply. your pc only has a 350w in it.
i would suggest the Nvidia 8800 GT if you dont have a budget or the 8800 GS if you dont want to spend too much.
both run 512mb and are superb for gaming. make sure you get some extra cooling in your pc so as not to overheat, these cards put out quite a bit of extra heat.
both are compatible with the dimension 8400.
