Windows 7: BSOD on Dell Latitude E6400 4 times day Error code 9f

BSOD on Dell Latitude E6400 4 times day Error code 9f

I am facing issues on my Dell Latitude E6400 laptop. Everyday it crashes with blue screen 4-5 times a day. Common symptoms are, when I move from wired network to wireless (wireless does not work and system hangs and eventually crashes), or when it is in a sleep mode. Sometimes, without switching to wireless also hangs and crashes. The blue screen says something like DRIVER_POWER_STATE_FAILURE and code 9f etc. I updated the Ethernet and wireless drivers too, but it didn't help.

It has Windows 7
- x64
- OEM version of windows 7 Ultimate is installed from Dell
- Age of system (hardware) is ~2 years. I got it now from my office IT.

I am attaching the zip file containing perfmon html report and files from Windows_NT6_BSOD_jcgriff2.

Will appreciate if you can help, what is going on and what needs to be uninstalled or upgraded.

Thanks for your post. I will do these things on Monday (with help from my IT guys, since they have privileges to uninstall McCafe). and will revert.

Thanks panais for your post. I guess the problem was two fold.
1. Cisco Deterministic drivers, which were causing the network to stuck.
2. There was a problem in the hardware as well. My IT team changed the motherboard and now it works perfectly fine.

Thanks for your help!!
