Irql_not_less_than_or_equal bsod

I have a brand new Dell Studio 15 running Windows 7 x64. I did a wipe and fresh install of Windows when it came in, along with installing all of the drivers.

I get the IRQL_NOT_LESS_THAN_OR_EQUAL BSOD only when I am in Windows and change the power source from AC to battery. It happens about 15 minutes after the change, and gives no indication ahead of time. If I shut Windows down and then switch power sources, everything seems to be fine.

I ran the Driver Verifier and it showed that all of the drivers were compatible. Attached are the files requested in a zip.

Specs:
Dell Studio 1558 Laptop
Intel Core i7 720-QM 1.6Ghz
ATI Mobility Radeon HD 5470
4GB DDR3 RAM
Fresh Install of Windows

Thanks in advance for the help!

Did you download your copy of win 7 or purchase it directly?

I purchased an OEM copy from NewEgg a few days earlier.

Maybe its just a bad disk? I'll see if I can ask my neighbor for his disk and do a clean install.

Ok. I wiped the system and used the Dell Recovery Disk to reinstall Windows (Ultimate x64). I still get the issue. After running the memory dump through Windbg, I see the following line at the end:

Probably caused by : ntkrnlmp.exe ( nt!KeSynchronizeExecution+3d59 )

Some sites say that this is a hardware issue, rather than a simple driver issue?

Right now, I'm gonna run Memtest86+ on each individual stick of RAM to see if thats the issue.

Hi -

If you have installed Daemon Tools again - uninstall it.

Look at RAM closely. Your prior OS install system logs show the Windows 7 memory test failed -

Code:

Event[33]:

Acronis may also be a problem here.

Follow Jonathan King's advice -- run the Driver Verifier.
