My problems started when I could not access the internet. Windows open the new hardware has been detected box a pci card. At this time I notice the network conection icon on the lower right was gone. Check the network conections there where none. I figured there was a driver problem so I turned off the computer an unplugged it and pulled the wireless card out to reload. Went to reboot and would not boot no video and the board gives me post error 25 No ploblems prior to this computer has worked great for years.
