Hi there, I'm inexperienced when it comes to PC's so i apologise in advance. After a recent thunderstorm my PC won't connect to the internet any more. I keep getting a message on the screen saying there is something wrong with my network adapter and i need to install the drivers. I've done some searching on forums for the last 3 days and have tried lots of solutions but keep drawing a blank. My motherboard is a Biostar A740G M2+ and the NIC is onboard. I've been running a 64bit version of Windows 7 home premium for 12 months which i upgraded from windows XP. Below is a list of everything i've tried already. I've checked BIOS to see if NIC is enabled which was o.k. I've done a loop back test ping 127.0.0.1 which came back 4 packets sent and 4 packets received. There are 2 lights on the NIC socket on the back of the tower 1green and 1orange. There is no network adapter tab in device manager. I can get this to appear by showing hidden devices but the onboard NIC isn't showing. The chipset drivers which came with the motherboard are all for Windows XP so I've downloaded what i thought was the correct chipset drivers for windows 7 from Boistar Europe and installed them with no change. I've completely unplugged the tower for 30 minutes and pressed the power on button to fully power down the tower as it as 'awake by LAN' option in the BIOS with still no change. Any suggestions would be appreciated. Thanks in advance.
