Hey I keep on getting BSoD by the error DRIVER_POWER_STATE_FAILURE.

it seems to be caused by halmacpi.dll and ntkrnlpa.exe

The computer I am using is HP tx2 loaded with Win7 Pro 32 bit.

Please help me find the solution for this problem as I am out of ideas and do not know how to read dmp files.
 

Solution
I did a clean install, but before I had Windows Vista and had no problems.


How can I fix the driver causing the problem?

And thanks guys for the quick reply!

The DLL: halmacpi.dll is used by your ACPI Processor.
I'm not entirely sure how you could uninstall it.
But have you tried running Windows in safe mode?
