My Nvidia GT630m graphics card is showing a yellow traiangle in device manager. When you go to properties you see an error code 43. I have tried OEM drivers and the latest from Nvidia for it. Also when I install the drivers the Nvidia control panel in advanced is not visible even to be selected, but after it is in the control panel but never opens. I have also tried back drivers from nvidia from as far back as 326.xx.


Secondly when it was working correctly whenever I started a game the driver kernel would crash and the game would not start. I was laying Crysis 2 only at the time. Googled the problem and there were suggestions of selecting high perfomance in the nvidia control panel but that did not work as well. I wiped my hard drive and perfomed a clean install with Windows 7,8, 8.1 and 8.1 update still no change.

The difficulty with troubleshooting problems with laptops is that hardware parts are almost impossible to swap out to test (in most cases).  All I can offer is a few tips that I have found useful when dealing with these kind of problems in laptops:

> First, if your laptop is still under warranty, that is where you should start first. Also remember that Nvidia may have warranties on their component that is still in effect after the Lenovo warranty expire. Explore that possibility.


I wiped my hard drive and perfomed a clean install with Windows 7,8, 8.1 and 8.1 update still no change.

> Remember that when you nuke your hard drive and reinstall Windows, including different versions, it is extremely important that you also install the motherboard drivers for that version of Windows. Many people overlook this, and have resulting problems. Without those drivers, the machine defaults to the generic Windows drivers that may or may not work properly, or at least up to proper level of performance. If you are simply restoring the OS from a restore CD or restore partition on the hard drive then the drivers are included and there is no problem. However, if all you have is a restore partition, and you actually wiped the entire hard drive, that partition is gone so you must contact Lenovo for the drivers for your unit. You may be able to download them off Lenovo's website, we can hope for the best on that.
> I would have suggested a system restore attempt first, but if you have wiped your drive that is no longer an option.
> I assume that you have not been making regular HDD backups, especially image backups, so that is not an option.

> Here is some information on your lap and Nvidia card problem:



If I can think of any other suggestions I will post back.

thanks a lot.


  • The recovery partition you speak of is is gone when my drive died some time back.
  • I checked with the Lenovo support site for my laptop and upgraded the BIOS drivers for Windows 8 and 8.1 but I still have the code 43 and a yellow triangle in device manager. As for restore CDs mine did not come with them and from looking around I can order them but my country is not supported so I will have to find a way to get them if I decide on that course of action.
  • As for the last solution I posted that on tomsharware.com but the problem has come back.

I will try continuing looking for a solution. This usually happens when I do not play games for a while.
