Compaq Presario C738TU Windows 7 Driver

Ok, here is my suggestion for drivers, test it and report which works and which not, the main problems is with the audio which is Conexant High-Definition Audio Driver, anyway hope this drivers works and report the progress.

Some drivers will automatically install
note that for every installation i recommend to right click and select run as administrator
