Hello, I really need help with my Compaq Evo D5 Desktop PC! I had Audio and everything was working perfectly, then I installed Windows Xp Professional Black Edition then, some of the Drivers had an Yellow exclamation mark next to them so I Updated all those Drivers including my Audio Driver. Now all of the drivers are installed perfectly but the Audio is out! the lil speaker symbol from the taskbar on the right bottom corner of taskbar is gone! but when I try to update the driver it says that the latest Audio Driver is already Installed, Can Somebody Please help me?? Also I tried going to Compaq/HP tech website and downloaded the Audio driver, but when I try to install it it says " No Driver Found " in the middle of the installation process! Please help me on this matter.
