I have an Acer Aspire AX3900 desktop. Due to replacement harddisk I had problems re-installing windows 7. So I installed a windows 7-version from a DVD that was delivered with my son's laptop. This windows 7 version only worked well for a limited time. After some time I received a notice that my Windows was no longer genuine. So I installed windows 10 (education). I cannot return to windows 7. Screen performance with my ATI Radeon HD4650 is not so great in windows 10. Is there a chance on getting a driver for this graphic card that is more appropriate for use with windows 10?
