i have intel DG31PR i tried installing vista 64 bit as a second OS but it was so pathetic that i had to delete it and come back to my XP.. but when i tried to access network..it gave me a message that i don't have a eathernet device on my board..sound is also gone and no device is detected..i tried installing drivers but they are not of any help..in device manager i can see two PCI devices and an ethernet controller in yellow which comes under other devices..i have tried to upgrade BIOS and firmware of the MB but still im facing same probelm..

I even installed fresh copy of windows but im facing same problem
