My system is windows 8 pro rtm x64. Recently my system started hanging frequently. Nothing but the restart button works. But now just after hanging it showed me a BSOD error saying watchdog violation. I used bluscreen viewer to see the error in the memory dump and it showed me something about hal.dll, ntoskrnl.exe. This is what windows showed me.

Code 133 translates to ERROR_INVALID_LOCK_RANGE (A requested file lock operation cannot be processed due to an invalid byte range.) The issue is likely happening either within windows firewall, the hardware abstraction layer (hal.dll), or a network driver or firewall you have installed.

Try running windows update and also ensuring that your network drivers are up to date. If you have installed a 3rd party firewall, update or uninstall it. It would also be worth doing a memtest. If that doesn't help, you will probably have to rebuild.
