Intel HD Graphics 4600 driver issue

Baz J 40

Intel HD Graphics 4600 - Graphics driver not updated and won't start.

The driver for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

I cannot find an update on Microsoft or Intel? Any ideas please?

It might make sense to also contact the hardware manufacturer. (There is a community).

By the way, the product seems to be old and discontinued.

Hello David, thank you for your reply. This is my wife's PC and we both have the same although mine is a different spec, AMD, not INTEL, anyway I thought OK I've spent to much time on this problem and put her hard drive in my PC and all was fine. I then decided I would try my hard drive in her PC, the graphics driver worked fine. Now the SM Bus driver is showing the yellow triangle and I can't find an update for that driver. Although the PC appears to be working OK now! I'll have another look tomorrow I've had enough now. I've now put my wife's hard drive back into her PC no problem with the graphics driver just the SM Bus driver.

Thanks for the details.

Usually, the warning (yellow triangle) in the SM Bus Controller can be resolved by installing the latest Chipset driver provided by the computer manufacturer from the support area of their website.

If you can't find the driver, please share a screenshot of the system information from the affected computer, and I'll help you.

Feel free to ask any questions you may have.

Answer 2

The error message you are encountering indicates that the driver for your Intel HD Graphics 4600 has been blocked from starting due to known compatibility issues with Windows. This is represented by the error code 48, which suggests that the driver is listed in the Windows Driver Protection database as problematic.

To resolve this issue, you should obtain a new driver from the hardware vendor. Here are some steps you can take:

Visit the Intel website: Check for the latest drivers for your Intel HD Graphics 4600. You can search for the specific model and download the appropriate driver.
Contact your hardware vendor: If you are unable to find a suitable driver on the Intel website, reach out to the manufacturer of your computer or the graphics card for assistance in obtaining a compatible driver.
Windows Update: Make sure your Windows is fully updated, as sometimes driver updates are included in Windows updates.

If you continue to have issues, consider checking forums or support communities for additional guidance specific to your hardware configuration.
