My operating system is Windows 7. My video card is ATI RADEON HD 4300. In "Device Manager" it is missing the driver. I downloaded and installed a lot of software from AMD and perhaps not remember them all: autodetectutility /---/ 13-9-legacy_vista_win7_32_dd_ccc_whql /---/ radeon-crimson-16.8.3-raidxpert-utility-win10-win8.1-win7-32bit /---/ whql-win7-32bit-radeon-software-crimson-16.9.1-sep13.
But the problem persists. I am available to give you other useful information. Please help.
