Search the web for amd_chipset_drivers_am4_tr4.zip
Extract the zip but don´t install.
Update manually the device driver and select the extracted folder.
That´s worked for me.
The device is AMD PSP 11.0 Device
its ok guys. had to reinstall windows recently and the problems gone now. it was something to do with audio and i had to download it separately from the chipset drivers but its all good. thanks for the help.
