need sd driver for hp pavilion down graded from win 8 to 7pro 64 bit
have been told by HP suport, that there is no compatibility and none available for an sd card reader on my model # p7-1436s which came with win 8 but was down graded at point of purchase to win 7 pro 64 bit. computer is running CAD-CAM systems and has to be in win 7 format but there seems to be no driver cross over for the sd card reader. cpu sees the card but does not load the card information or even show it in the computer icon pull down showing what is in the cpu.
sd card works perfectly in another cpu, so problem is in mine.
