    Is it possible to uninstall the Display Adaptors and still have video output?
    Because this is what you've done apparently, you have no Display Adpators in the Device Manager. See my pic attachment. (office PC).

    Is it possible you are running off on-brd graphics? Is your monitor plug into the video card or some video connector on the mobo?

    Thanks Kirock.
    Ha, apparently I seem to be able to do that yes! What's that all about!
    My monitor is plugged into my Nvidia card at the moment. I can run it through the motherboard but only if the card is removed.

    I don't know what's up with that, it is pretty weird. Make sure your Plug and Play services are enabled and started. Start/Run cmd/type "services.msc" (w/o quotes). Also reboot and enter the BIOS, check that the AGP X4 or X8 is enabled and turn -off on brd graphics.

    Thank you again Kirock.
    Plug and Play services are enabled, I'm off to check the BIOS

    Everything fine in the bios it seems.
    I did notice however that on boot up, the first thing I saw was
    before the usual appears. So it seems to recognise it's existence somewhere!

    Try running an sfc scan. use start-->run--> sfc /scannow . This should find any missing windows drivers and hopefully fix the missing display adaptors in DM.
    (you'll prob need the XP cd in the drive to complete it).

    Thanks Kirock. Tried that and nothing changed unfortunately.
    I'm really pleased with all you folk's help. I'm sorry I don't seem to be getting anywhere near the answer. Nvidia site was no help. They mailed me to ask me to make sure the card was plugged in properly! :mad:
    I really don't want to format my HD and start again with all that entails. Any more suggestions would be recieved gratefully.
    Again, many thanks.

    I think you're going to have to try a Windows repair. Do NOT do this from the Recovery Console. Follow these instructions here:

    You will need to reinstall any service paks when you are done.


    Edit: I forgot to ask have you tried a system restore?

    Hi Kirock,
    Thanks. I tried windows repair but still no recognition of card.
    System restore didn't go far back enough to when I got the pc last year. Perhaps the only thing left is reformatting but I really want to use that as a last resort.
    I'm learning a few new things from all your good advice though and it's great you and the others have taken time to help me.
    I would be grateful of any other advice. I will post here any resolution so that it can be shared with anyone else with a similar problem in the future.
    Much obliged.

    Hello all.
    You might like to know that my PC now recognises my display adapter!
    I had a moment of clarity tonight and tried the motherboard installation disk. I ran the SiS AGP PCI-to-PCI Bridge Driver and then restarted. The XP balloon appeared and told me it had found new hardware - my graphic card! Yahooo!
    If only I'd just done that to begin with ...I hear you!
    Thanks to all for your help, really. It was much appreciated. I learned a few extra tricks.
    I hope someone finds this useful should they find themselves with a similar problem.
    Many thanks

    Excellent! I thought you had tried updating all the mobo drivers so that solution never occurred me. Glad you got it fixed. Did you get the lastest drivers installed ok?

    Hey Kirock,
    Guess you can't overlook anything with novices like me! :giddy:
    As soon as it discovered the card it found the drivers itself. I assume they're the latest but then, maybe I'd better check. Just worried about fiddling with it now! LOL
    My display is working much better though now!

    Hi Ram,
    It might not work just the same but if you remove the card and connect the monitor into the motherboard (assuming you can) it should boot normally. (If not it must be something else) All I did was use the motherboard installation disk and I ran the SiS AGP PCI-to-PCI Bridge Driver (or equivalent). Turn off. Put your card back in and connect the monitor and hopefully it will recognise your card.
    I did it slightly differently in that I tried an XP repair as suggested which, although the monitor was connected to the card, it stopped it turning off at bootup. It meant I had to reinstall SP2 and all the updates again which went mostly ok. Some programs may need to be reinstalled.
    Any help?
    Let me know

    It's not the same problem. You can see the Windows logo and then it reboots right (or hangs)? This sounds like a HDD boot sector failure/damage. I.e. when you moved the PC).
    Do you have the Win XP cd?

    Ok when I plug my monitor cable into the video card the screen goes blank, but when I plug it back into the original mohterboard slot the screen is normal. At first I thought it was the monitor so I updated my monitor into the plug and play, but still no solution. I have a sony vaio desktop model: PCV-RX741. I went into the control panel-> settings and disabled my sis. Is that the right thing to do? Then I also uninstalled the sis570 or something like that in the add/remove programs. Is that the right thing to do? Overall, the monitor is blank when the monitor cable is plugged in the video card. Please help me, my desktop icons are large and I cannot change it back even though i went into settings in properties. It makes you really dizzy and i have to strain to even type this right now. Plus i also installed the nvidia drivers.

    Hi Fusi0n,
    I'm sorry, I don't know how to help you. I needed help here myself but you could try visiting the Nvidia site and find the FAQ's in support which may help. The thing that helped me was running the disk for my motherboard which solved my problem. You may also like to make your question a new posting in the forum which might be seen by more folks. Good luck. GD

    fuziOn: what you've done is uninstall the video drivers for your on-board video. This is why your icons are huge. What you need to do is this:
    1) Open Device Manager and uninstall the new video card and it's driver.
    2) Reboot and hold the DEL key to enter the BIOS menu.
    3) You have to turn -off the on-board video. Should be in the PCI Device Configuration menu.
    4) Save and Exit, reboot.
    5) Allow Windows to find the new video card. (it must be installed in the motherboard).
    6) When Windows finds it, it will ask to install drivers. Cancell the auto-install and direct the browser window to the video card's driver CD ROM or Floppy disk.
    7) It will probably need to reboot to complete installation, when it finishes and you're back to the desktop, right click anywhere on the desktop and select properties. Now set your resolution so your icons are the right size again.
    8) Almost done! Now go on-line to the video card manufacture's website and download the latest video driver for your new card. (the one shipped with the card is usually a year old already).

    I'm having somewhat of a similar problem. On startup my monitor will goes completely black. I can turn it off then back on and it will show what i'm doing for about 5 seconds then go black again. BUT if i turn on my computer and open the Disk Drive and keep it open the monitor will not go black. please help me on this.
    Danke, James.

    Ok, I'm having a similar issue with a PCV-RX741 (Sony VAIO dekstop) with the SiS 740 integrated graphics. I would like to upgrade the graphics with a PCI graphics card, and I'm currently researching to see if its possible.

    The next trick seems to be getting the computer to recognize the PCI graphics card as the primary video source. For some people it seems that disabling or uninstalling the SiS graphics drivers/hardware in Hardware Manager is sufficient to get Windows to use the PCI card as the primary, but for others it seems this doesn't work and they then hunt through the BIOS trying to turn off the Integrated card, but are unable to do so. One person said there were options for the amount of memory to allocate to the integrated graphics (16,32,64 or something), but not an on/off option.

    Was the proper installation of the new graphics card drivers (after the uninstallation of everything associated with the SiS graphics) all that you needed? Or were you able to toggle a BIOS setting or something?

    Which steps in Kirocks 8 fold path a few posts back worked for you?

    The only other thing that I saw online was someone mentioned that which PCI slot is used for the new graphics card might affect things due to some kind of conflict on the BIOS level (over my head...). They seemed to think the top slot would have the best chance of working because of some kind of shared resources between the top PCI slot and the integrated graphics. Anyway...out of curiosity...which slot did you get it to work in?

    Any feedback would be greatly appreciated! This thread is a testament to the awesomeness of online tech support!
