IT Home reported on August 5 that some users recently reported that their computers with old processors experienced a blue screen crash after installing the latest version of NVIDIA graphics card drivers. After verification, it was found that this problem was caused by NVIDIA's termination of driver support for processors that do not support the POPCNT instruction set.

According to IT Home, the POPCNT instruction set is an instruction set used to quickly calculate the number of 1s in a binary number. It is more common in modern processors. However, some older processors, such as the Core 2 Duo series, do not have this instruction set. NVIDIA clearly stated in a technical document thatStarting from driver version 555, NVIDIA graphics drivers no longer support processors that do not support the POPCNT instruction set.

When users install 555 or higher version NVIDIA graphics card drivers on these old computers,The system will have a blue screen error of "system thread exception not handled", causing it to fail to start normally.It should be noted that Microsoft has long announced that it will no longer support Windows 10 and 11 systems running on processors that lack the POPCNT instruction set, but the incompatibility of the NVIDIA driver has further exacerbated this problem.

Although there are relatively few users who use old processors with high-end Nvidia graphics cards, this is undoubtedly a problem for some users who still use these hardware. In order to avoid automatic driver updates causing system crashes, these users are advised to manually turn off the driver update function in Windows Update.

Although the affected user group is relatively small, this problem still causes trouble for some users. If your computer has a blue screen after updating the graphics driver, you may want to check whether the system supports the POPCNT instruction set.
