Windows 7: Help interpreting minidump

Help interpreting minidump


I've been getting random BSOD for the past couple of weeks with the message The computer has rebooted from a bugcheck. The bugcheck was: 0x00000019 (0x0000000000000003, 0xfffffa8005839558, 0xfffffa80096efb60, 0xfffffa8005839558).

Can someone take a look at the minidump and point me towards what might be causing the issue.

Do you have any virtual CD emulators installed, like MagicDisc? If so, I would recommend uninstalling them competely.

They often use sptd.sys, which causes a lot of BSODs.

The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arg1: 0000000000000003, the pool freelist is corrupt.
Arg2: fffffa8005839558, the pool entry being checked.
Arg3: fffffa80096efb60, the read back flink freelist value (should be the same as 2).
Arg4: fffffa8005839558, the read back blink freelist value (should be the same as 2).

Thanks Johnathan. I do have Daemon tools installed but that's been there for a couple of months without any issues.

I noted that nvlddmkm.sys gets a mention in the dump. I installed a beta version of the Nvidia driver a while back that I've uninstalled today. So I think it might be that.

I'll give it a few days and if there another BSOD try removing Daemon tools.
