Windows 7: BSOD on Windows 7 Professional 64 bit

BSOD on Windows 7 Professional 64 bit


I've bought a new computer and installed Windows 7 Professional 64 bit.
Everything was going great for two weeks until I've started playing with Winpcap 4.1.1 (compatible with Windows 7) - WinPcap, The Packet Capture and Network Monitoring Library for Windows.
When I'm doing different stuff with it (can't say exactly what) and also surfing the web (when I do both at once) I get a BSOD.
This is pretty consistent and I can pretty much decide when to get it.

It looks to me that the crash has something to do with the network device driver.
I've installed the latest drivers but I still get the BSOD on demand.
I do want to work with Winpcap and it looks to me that it can't be Winpcap's fault if I get BSOD (but I could be wrong) but some driver.

Attached are the 6 mini dumps of the BSODs I got so far.

If you have any idea on how to try and resolve this problem it would be highly appreciated.

Do a system restore to a point before you installed WinPcap and see if your problem continues...

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.

I'd have a question or two about it, but since you say "(can't say exactly what)", I'm hoping the info I gave already will help.

Thank you for your replies.

I can't restore the problem without Winpcap.

VSTesthost is the application I run that uses Winpcap (it's a unit test in Visual Studio 2008 that uses Winpcap libraries).

My guess is that it has something to do with Winpcap's npf driver.

If you have any more thoughts let me know.

Thank you.

I haven't used that in a while, but does WinPCAP show in the local area connections settings, where IPv4 and IPv6 are?

If so, I don't think any further software is needed to "run" it and have functionality.

Like I said, it's been a long sorry if I'm off here.

Try Wireshark out. It's an interesting piece of software in itself.

torrentg, I'm not sure what you mean.
I don't understand what you're trying to say and how is it related to my BSOD.

I'm familiar with Wireshark pretty well.
