Solved Windows 7 - BSOD 0x000000d1 IRQL NOT LESS OR EQUAL at Random moments

[Aleksis]

I have an Alienware M17xR3, bought it on january 2012. My first BSOD occured I think it was around September, but only once so I didnt pay attention to it. But since 3 weeks ago, I have BSOD frequently, sometimes 3 or 4 times a day, then maybe 3 days without any problems, and then again more BSOD.

It happens at random moments, either while playing, browsing, watching videos, or when I leave the laptop on during the night. I've never experienced overheating in this laptop. I don't do much downloading or anything like that. I may say that the laptop havent crashed yet when Im working on excel or word.

I have checked the hardware status using alienware autopsy, and all of them passed the test, also did Full virus Scans many times, and no threads were found. I checked for some driver updates but all the diagnosis I use tells me the drivers are up to date.

The crash used to point the Razer synapse was the cause of the BSOD, but since I updated that, the crash seems to point somewhere else.

The dump files are attached, Im not so pro at these tech things, But I read a lot and follow all the instruction. Pls help

Daemon Tools:-

Please uninstall DAEMON Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

Ok.. So I did everything you told me to do, it took me a while.

The only thing I didnt do was "Update drivers for NETwNs64.sys Intel(R) Wireless WiFi Link 5000 Series Adapter Driver for Windows 7 from Intel Download Center"... Because my Network Card is a Intel(R) WiFi Link 1000BGN, and I couldnt find any Intel(R) Wireless WiFi Link 5000 Series Adapter Driver from Intel Download Center... But I did updated my network card driver to the latest version..

Apart from that, I did the rest step by step..
So, if any BSOD comes again, Ill post an update.

Thnks for the quick reply
