I have a desktop Windows 7 Home premium 64-bit (Aspire M3970) which was working fine until, this update KB3004394 from windows on 12/11/14. Microsoft has since removed the oriinal update from its pipeline, but it has already cause alot of issues with my computer. It has configuration problems that prevents it from working properly, the Intel (R) HD Graphics is reporting "52" Video Controller 1 is not available, the device MS/MS-Pro/HG cannot start properly, or may be experiencing a hardware failure acording to "Resource and Preformance Monitor". It tells Video Card does not support Aero effects and i need to update the driver for my video card.Contact or go to manufacturer website and download driver, but i don't know which ones i need to download. Can someone help!!
