I have just had a big update of win 10. Since that my Radeon 4200 driver has not worked After start-up I get the messaage :
HWiNFO AMD64 Kernel Dricer REALitm)
Windows blocked the installation of a digitally unsigned driver.
Uninstall the program or device that uses the driver and check the publisher's website for a digitally signed version of the driver.
I would appreciate advice on how to do that.
The device manaager shows Radeon 4200 as the installed display driver, but the system is actually running the windows basic driver.
If I try to run and update for the 4200 the program says it is already the latest version.
Can anyone help me please?
There are no Windows 10 drivers for that GPU. The HD4xxx series has reached peak optimisation and been moved to legacy status, there will not be any further driver updates for your product. More information available here.
