Debugging BSOD

I have repeated BSODs, but unfortunately my system doesn't seem to write minidump/kernel dumps!! I don't know why, because everything is set to!

However, on one of the three or so crashes I got in a day I did get a dump write, and analyzing it with windbg I found that it was probably a driver called ntkrnlpa.exe, whatever that is. Because I only have that one dump I cannot tell if that was the primary and consistent cause, or even if it was accurate, but I have included the bang analyze dash v and lmv results for this debug, if anyone can add any wisdom to this irritating problem.

Thanks,

Scarlet


(the lmv results extend much farther, but I only included the info relevant to the driver hinted by !analyze -v...)

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 71a5df52, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000008, value 0 = read operation, 1 = write operation
Arg4: 71a5df52, address which referenced memory
