First of all here are my specs: Computer is an E-Machines T2642. Motherboard: IM845GV OS: Windows XP Home Edition (service pack 1) Now my problem. About 4 days ago my sound stopped working on my computer. I checked the device manager and found multimedia audio controller listed as an other device with a question mark next to it. The properties lists the device as not having any drivers installed. I have tryed installing and rolling backthe drivers to no effect. Another problem that I seem to have is my network connections shows a local area connection as having a network cable unpluged, with the device name being Realtek RTL8139/810X Family PCI Fast Ethernet NIC. I have tryed unintalling the realtek device and adding it again, but when I do it seems to generate the unknown multimedia audio controller which I suspect is the source of my problem. So any advice on what exactly I need to do to fix this and get the sound back? At this point I suspect that the "sound card" on my motherboard may be fried. Help would be appricaited.
