Both errors are 0x7F: UNEXPECTED_KERNEL_MODE_TRAP
One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause (many dozen KB articles exist for this error referencing specific hardware failures) and, of these, memory hardware failures are the most common.
The driver cited is ACPI.sys which is Automatic Configuration Power Interface and is a core Windows driver which will attempt to throttle CPU usage when temperatures get too high (and other power management operations).
