I have an HP Pavilion dv7 Notebook PC; 64-bit, Windows 7; Intel Core i7 CPU Q720@1.60GHz I am regularly getting blue screen DRIVER_IRQL_NOT_LESS_OR_EQUAL with tcpip.sys mention. Please see Minidump.zips here: https://skydrive.live.com/#cid=42B07EA20D0FCE3B&id=42B07EA20D0FCE3B%21107 I tried to open/view these dmp files, but I am unable. Any idea what might be causing this issue? Recent software updates: Pentaho PDI (Kettle ETL), PC Tools Spyware/Antivirus/Firewall, WinSCP, ToirtoiseSVN, regular Windows updates, HP Wireless Printer (drivers)

With it being the same file each time, check to make sure it is the proper Microsoft version. The file and product version from a fully updated Windows 7 Enterprise SP1 64bit is 6.1.7601.17697.

Thank you, Darien, for the quick response. You mention to check that "it is the proper Microsoft version." What do you refer to as "it"? I am not sure what to check or how to check it. Thanks!

Navigate to c:\windows\system32\drivers. Right-click the TCPIP.SYS file and look at the details tab. The image below shows one from the Windows 8 DevPreview. The version you want to see is 6.1.7601.17697.

Looks like I have the correct/latest file version: 6.1.7601.17697 Any other ideas/recommendations? Thanks!

My computer passed 100% on the Memory Test - no memory failing. What should I try next? Is there an easy way to read/interpret the minidump files? Thanks~

This problem continues to persist. Every 1-2 days, I crash with the same error. I have verified it is not a memory issue. But I do not know what to check next. Can anyone point me in the right direction? What should I try next?
