What You Should Know About Driver Updating

There are numerous of popular warnings along with other messages which you may get in the driver updating procedure, several of which I've paraphrased and listed here along with guidance on how to proceed:

Windows requires a digitally signed driver: You won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue, in 64-bit versions of Windows. If you see this message, end the driver update process and locate the correct driver from the hardware maker's website.

QUESTION: I have seen this Event Log Message:

                A TDR has been detected.
                The Application must close.

ANSWER: If you received this message from an application (on a pop up message or in the Event Log), the application was unable to continue rendering because the Microsoft Windows imposed time limit (TDR) was exceeded. This is normally the case when the workload sent to the Graphics Card is greater than what the graphics card can process in the normal timeout of two seconds.

Two possible solutions to try would be:

1. Reduce the graphics workload if possible, such as rendering to a lower resolution or with less detail.

2. Update Graphic driver. You can download DriverTuner and let it update your drivers automatically.

To download and update the driver for NVidia Quadro K420 yourself (If you are a geek)

It's best to let Windows install device drivers automatically. But if Windows can't find a driver for your NVidia Quadro K420, you can look for a driver on the manufacturer's website of NVidia. Driver updates are often available in the support section of such sites.

Once you find the updated driver, follow the installation instructions on the website. Most drivers are self-installing—after you download them, just double-click the file to begin the installation, and then the driver installs itself on your computer. But make sure your are downloading drivers from a safe website to avoid virus attack or registry corruption. Download a professional driver updater or find a geek to help you.
