Some times my video card driver (Intel GMA X4500HD) crashes and gets restarted automatically. But more often (almost every time I watch a flash-powered online video for a period of time) it just gets slower and slower and extremely slow until I restart my computer. This looks like a resource leak in the video driver code and I'd like to try restarting it alone without restarting the whole system. How do I restart it (or cause it to crash immediately to be restarted automatically by the OS) manually?
Devcon tool from Microsoft.
Using DevCon, you can enable, disable, restart, update, remove, and query individual devices or groups of devices.
To list display devices use the following command:
devcon listclass display
To restart a device use the command:
devcon restart "class id"
devcon restart "PCI\VEN_115D&DEV_0003&SUBSYS_0181115D"

- Copy "DEVICE NAME" to clipboard for use in the script: for example: "NVIDIA GeForce GTX 260" or "AMD Radeon HD 7900 Series" Open notepad and copy paste this code:
@echo off echo. echo *** Restarting GPU timeout /t 2 /nobreak >nul devmanview.exe /disable_enable "NVIDIA GeForce GTX 260" echo. echo *** DoNe timeout /t 2 /nobreak >nul taskkill /f /IM explorer.exe explorer.exe
Remember to change "NVIDIA GeForce GTX 260" to your Graphics card name taken from ..\windows\system32\devmanview.exe
Save the notepad file as a
