Windows 7: Irql_not_less_than_or_equal bsod

31 Jul 2010   #11

Win 8.1

Ok. I ran the Driver Verifier and followed the instructions. After using the system for five or six hours with it enabled, I was unable to replicate the previous blue screens.

I also looked up this issue on some other forums and found that one particular person had this exact same issue with the exact same system (Dell Studio 1558). He claimed that it was a defective Bluetooth Chip.

I have since disabled the Dell Wireless 365 Bluetooth via Device Manager. So far, there have been no issues. Later tonight, I'm gonna run Memtest86+ again for a few more hours just to make sure its not the RAM. I called Dell and they will issue a complete system replacement in about two weeks, just incase it happens to be both the Bluetooth and RAM.

And thanks for all of your suggestions so far...and happy late SysAdmin Day to all at Windows 7 Forums
