|There is an Asus P4P800 SE motherboard with onboard sound card on my computer. I have CD disk that i have purchased with motherboard and i have Windows XP SP3 install disk.|
After assembling the computer i installed XP SP3 on it. Then i installed other drivers from motherboard disk. XP was running on my PC very well. But one day after some power interruptions two problems occurred. There is no sound and PC could not detect USB flash drives. To solve this problem i uninstalled corrupted SoundMax driver and tried to install it again from P4P800 SE disk and received a message: the driver not found, restart PC and try again. I did it but result was the same. Then i formatted disk C and reinstalled Windows XP again. After reinstalling XP i installed chipset drivers (successful) from CD-disk as usual, then tried to install SoundMax driver but the result was the same: The driver not found........ In the device manager of course there was no sound device. When i try to install USB drivers from disk there was message that SP3 includes all drivers. In the device manager everything is all right with USB but computer does not detect any USB flash drives. There is no power to USB ports. Computer power supply works properly.
I have reset BIOS to default settings. I have cleared RTC RAM. I have even updated the BIOS. No results. May the motherboard south bridge chipset be the source of the problem? I keep in mind that exactly the south bridge controls onboard sound card and USB ports. What to do? Help please.
