I've been getting the BSOD a few times a week since I bought my lap top. It's a Dell Vostro 1520 with Windows 7.
The BSOD always says reference by pointer, I can't figure out what is causing it.
Attached is a zip file with the mini dump information.
Any help is appreciated.
Hi BK and welcome
this one is pretty straight followed. Its your PCTools, specifically PCTCore64.sys. I would uninstall it and see if the problem goes away. You can always re-install it later
I would also run a system file check
start>cmd>right click and run as admin>sfc /scannow
Let us know the results
good luck
Ken

Each time a driver uses a pointer to an object the driver calls a kernel routine to increment the reference count of the object. When the driver is done with the pointer the driver calls another kernel routine to decrement the reference count. Drivers must match calls to the increment and decrement routines. This bugcheck can occur because an object's reference count goes to zero while there are still open handles to the object, in which case the fourth parameter indicates the number of opened handles. It may also occur when the object’s reference count drops below zero whether or not there are open handles to the object, and in that case the fourth parameter contains the actual value of the pointer references count.
