I recently built a computer for a friend, with a gigabyte m68m-s2p mobo, amd sempron 2.7g , 2gb ram, 480 psu, with a dvd burner and 1tb hdd, windows 7 32bit. It was working fine after installing windows and updates, but after sending it to my friend, it is having issues out of the box. Direct connection to modem there is not internet connectivity, and network/sharing says unidentified network, also when unplugging the ethernet cable from the computer, it restarts. I thought I had made sure to update the bios and the chipset/lan etc, but I could be wrong. Any suggestions?
