In most cases, this error occurs because the graphics card driver is outdated. You need to upgrade the driver of your graphics card to the latest version. An outdated, corrupted or incompatible driver can get your system into display this blue screen. Outdated drivers and overclocking softwares, or a recently overclocked tweak are also known to cause this. If a recently installed program or a driver caused this issue; then the first approach should be to uninstall them since they are simply not compatible, keep track of updates and attempt reinstall when a patch or update to the driver has been released.
In order to fix this issue, the computer must be restarted in safe mode. Once after booting the computer in Safe Mode, you have to uninstall the incompatible device driver from the Device Manager, and then download and install the latest drivers from the manufacturer’s website. If you are lucky, the “system_thread_exception_not_handled” error code will have a file name attached to it, indicating which graphic driver is causing the problem. If you update or repair this graphic driver, you will be able to resolve the error completely.
