Bugcheck code: 0x1A (0x41201, 0xFFFFF6800001A338, 0xBD800001F4FD4867, 0xFFFFFA800C9BC8E0)

Bug check description: This indicates that a severe memory management error occurred.
This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
