Poor CPU cooling due to a CPU heatsink and case fans (or filters) that's clogged with dust or has come loose. Overclocking beyond the highest clock rate at which the CPU is still reliable. Failing motherboard. Failing processor. Failing memory. Failing I/O controllers, on either the motherboard or separate cards. Failing I/O devices.
In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...

Processor exceptions generated by the CPU have fixed mapping to the first up to 32 interrupt vectors. [1] While 32 vectors (0x00-0x1f) are officially reserved (and many of them are used in newer processors), the original 8086 used only the first five (0-4) interrupt vectors and the IBM PC IDT layout did not respect the reserved range.
The CR0 register is 32 bits long on the 386 and higher processors. On x64 processors in long mode, it (and the other control registers) is 64 bits long. CR0 has various control flags that modify the basic operation of the processor. Register CR0 is the 32 Bit version of the old Machine Status Word (MSW) register. The MSW register was expanded ...
While the machine state register found in the PowerPC architecture and the model-specific registers found in IA-32 and x86-64 architectures fulfill similar functions and the initialism "MSR" can refer to either, there are important differences that distinguish them. The machine state register, a single register, provides coarse-grained control ...
The CPU supplementary instruction capability does not as a rule apply to 8 or 16 bit CPUs, as many of these CPUs are used mostly as microcontrollers. On modern 32 and 64 bit CPUs the processor supplementary capability does not extend to Floating Point Units (FPUs) or Memory Management Units (MMUs) as these are considered to be fundamental core ...
