I have a lenovo laptop z61m with Win XP. Up until 2 weeks ago, I was using wireless to connect to the internet (using the laptop's own wireless network adapter). I started to have some problems with it connecting, and even got several blue screens (Hardware, NMI: memory parity error..). I rebooted, but still was connecting less then 10% of the time. Assuming that the adapter was failing, I disabled it and starting using the wire to connect. With the wire, I can initially get to the internet, but stay connected for maybe 5 minutes. The laptop completely locks up, no response to anything I do, and the internet connection drops. The only way to recover is to do a hard reboot, then it all starts over again.
I also noticed the the network controller in System Devices has a yellow question mark. I just can't stay connected, even though I've got the wired connection.
Can someone help me out? Thank you.
