Today i had a problem with a Acer machine that kept rebooting just after the machine had started up Windows, typically a couple of seconds after everything was loaded. After managing to disable auto-reboot upon crash, i got a hold of the error message 0x00000050 (aka PAGE_FAULT_IN_NONPAGED_AREA ). After testing a “crash report analyzer” i noticed that the cupit was ”elock2fsctldriver.sys”, which comes from Acer`s eLock software.
So i booted into Windows Safe Mode, uninstalled the program, and then the machine rebooted without any issues. 🙂
(This was of course after testing all the hardware and drivers, which is normally the problem…)
