Hello gilsonal. Your crashes point to NETIO.sys
There are a few things that can cause this.
- needing to update your network drivers
- Your A/V McAfee is problematic
- P2P Networking (uTorrent)
So, for step 1, please update your network drivers at Lenovo's website. I don't have your model # for your laptop, so I can't link it for you. Go to Lenovo's website and look for the driver
For step 2, uninstall McAfee. http://service.mcafee.com /faqdocument.aspx?id=TS101331&lang=en_US&prior_tid=3&AnswerID=16777217&turl==http%3A%2F%2Fkb.mcafee.c om%2Finfocenter%2Findex%3Fpage%3Dcontent%26id%3DTS101331%26actp%3Dsearch%26viewlocale%3Den_US
For step 3, you may need to stop using your P2P for now.
For step 4;
