My laptop has started crashing often recently with blue screens (BSOD) and while waiting for the physical memory dump to be completed, the error states that it has something to do with 'tcpip.sys' I am absolutely clueless as to what is happening to my computer and is extremely desperate to get help for this issue. I would love for someone to please diagnose this and recommend a solution. I have attached the minidump file in this post.
I am using a Dell XPS 17 64 bit Windows 7 Professional.
Thank you very much!
