I am running XP with a matsonic motherboard MSKM 400-M. When I start my computer I cannot connect to the internet and my network adaptor is missing in device manager. If I then restart, I can connect my computer to the internet and my network adaptor appears in device manager.
I recently re-formatted my hard drive. The problem was there both before and after re-formatting. I have tried re-installing the network adaptor drivers but this did not help. When I reformatted the hard drive I could initially connect to the internet on startup. The problem re-occurred when I installed my antivirus software, AVG Free. I have tried starting the computer with the anti virus disabled but still had the problem. Can anyone help or do I just continue to start and then restart to connect to the internet.
