random frequent crashes with DRIVER_IRQL_NOT_LESS_OR_EQUAL

[idata]

Hi,

I have a VAIO laptop (VPCZ1) and I am getting frequent crashes.

Here is a log extracted using "whocrashed". I appreciate any help to understand and resolve this problem.

Thanks.

Possibly this problem is caused by another driver on your system which cannot be identified at this time.

I don't see anywhere which driver version is in use, but a good first step is to check which driver version you have loaded for your network interface. If your notebook manufacturer has a newer driver posted you'll want to start there, and if you still see issues then try the latest driver from our support website (link below.)

The latest version of the e1k driver is 11.12.36.0.

Another possibility is corrution in the TCPIP settings or the actual tcpip.sys file itself. This type of regular crashing (which usually reports tcpip.sys as the culprit, but occasionally blames the LAN driver instead) is documented in several places and often requires a reset or reload of TCPIP to correct. Your operating system manufacturer can help you with the exact command line or procedure to accomplish this.

One more idea, third party applications that modify the system's networking stack might also play a role. A general search engine query like 'tcpip.sys bsod windows 7' can net you some additional troubleshooting ideas and maybe identify some software on your machine that requires attention.

Please post back with your results, good luck!
