Hi everyone. I am new and not very good with PCs. I have an ASUS laptop A7J and I'm using XP Home. After my hard disk died, I had to get it replaced. I went to a PC store which changed it and reinstalled the hardrives from Asus website, but some of them do not work, including the Mutimedia controller. I have no sound and a question mark in my device manager in front of multimedia controller. In addition, I also have a "?!" in front of two lines "PCI device". I am living abroad and I don't have access to any of the drivers I received when I bought the computer. So, I have downloaded the audio hardrive from asus website and tried to reinstall it again but it does not work (The harware update wizzard tells me it can not find the necessary software). I followed some advises I found in related forum on Techspot. I deleted "Multimedia controller" from the device manager, reboot the computer. The PC tried to reinstall the multimedia controller, but once again I ended up with the same messages (The wizzard tells me it can not find the necessary software). There are so many other advises related to Multimedia controller on this website, that I don't know which one I should follow. I have asked for help to Asus support but they have not given me any answer yet. Would anyone know how to resolve this please? Thanks a lot.
