You can download the driver from AMD Download page link from here: https://www.amd.com/en/support/graphics/amd-radeon-hd/amd-radeon-hd-7000-series/amd-radeon-hd-7750
All HD 7xxx are not supported with Driver updates anymore from AMD so if you have Windows 11 installed and the Windows 10 driver doesn't work you would either have to downgrade to Windows 10 or upgrade your GPU card or let Windows Update install the compatible Windows 11 driver.
By the way, Visiontek Support is excellent. I had a Visiontek 6950 and needed a new Cowl with Heat sink and they sent me one for free even though my GPU card was out of Warranty already.
In the future for drivers go to AMD download page as mentioned by @spinalfailed
