Hi. I'm Wilfred@cav. Please help me fix my desktop. I reformatted from Home XP to Pro XP. After the formatting, there was no sound and I have this 2 yellow-icon things (PCI Simple Communications Controller and Multimedia Audio Controller) on the device manager, which says that I don't have a driver installed for this device. I don't know what to do. Please help. I'm now at work and the desktop is in my place and I don't have internet access in my place. I'll appreciate any help. Thanks.
