Graphics Card not detected on ASUS laptop

I ran a standard update that was recommended by warcraft and ever since then my nvidia 540M graphics card on my ASU N53S is not found..

i get "nvidia display settings are not available an nvidia graphics card was not detected in your system"..

Its been that long I cant remember what the exact update was.

I have tried everything that I can find suggested updating drivers etc but it simply wont detect it..

Help please

  1. Try downloading the latest drivers , then uninstall current and remove then load the latest
  2. I have a similar problem with an Asus U30Sd notebook, Windows 7 and Nvidia 520M graphics card

    A couple of weeks ago I noticed laggy screen performance and low FPS. I do not know exactly when the Nvidia card stopped working.

    (1) Windows Device Manager>Display adpators does not detect the Nvidia card. Only detects Intel HD 3000. There are no Device Manager errors or strange devices
    (2) Nvidia driver v267.21 does not detect card

    What I have tried:
    (1) Checked Asus website for driver updates. Found I already had the latest recommended BIOS (v213) and Nvidia driver (V8.17.12.6721 - ie Nvidia v267.21). This was because I had a similar problem about a year ago. That time I fixed the problem by upgrading to the Nvidia v267.21 driver. I do not remember if I could see the Nvidia card in the device manager before I fixed the problem.
    (2) Uninstall Graphics drivers, download and intall latest Nvidia driver from the Nvidia website v320.49 (recent stable release 1 July 2013). This did not detect the card.
    (3) Full system scans with AVAST and Malware Bytes-found nothing

    I do not know if the card is fried or if it is a software issue. Given that I had a similar issue caused by software a year ago I suspect software. I do not know where to go from here.
  3. You too, might try uninstalling and reinstalling, could have gotten corrupt from a crash, malware (not a bad idea to run MalwareBytes also), a virus.......
  4. Hi Tradesman1

    Thanks for the rapid response.

    When you say download the latest drivers do you mean the latest Nvidia graphics card driver or other drivers as well?
  5. Primarily yes, but if any other mobo drivers need updating, those too
  6. Thanks for the replies..

    I've run virus scans and nothing... Which drivers should I be checking? I'm a bit of a noob when it comes to this sort of thing
  7. Check all available, there will be a release date which may give you and idea, if not sure can go to DEVICE Manager in Win and check driver versions for things to see what versions you are running
  8. Hey

    A friend of mine had the same problem Have you tried forcing an unexpected reboot , You see the drive hooks a function by patching the system core table so it's not safe to unload it unless another thread is about to jump in there and do its stuff. And you don't want to end up in the middle of invalid memory. Lol
  9. Just providing an update.

    I eventually performed a full system restore to factory settings which is available on ASUS laptops. Still could not detect the nvidia card

    Laptop was under warranty so I sent it back to ASUS. Came back fixed. They claimed they just performed a system restore and did not replace the card. Did not provide any further details.

    Frustrating not knowing what went wrong. There are lots of similar complaints about ASUS laptops with nvidia cards on many forums but I could not find a solution that worked.
