Machine Check Exception - Problem Types

Problem Types

Most of these errors relate specifically to the Pentium processor family. Similar errors may occur on other processors and will cause similar problems.

Some of the main hardware problems that cause MCEs include:

  • System bus errors (error communicating between the processor and the motherboard).
  • Memory errors that may include parity / Error correction code (ECC) problems. Error checking ensures that data is stored correctly in the RAM; if information is corrupted, then random errors occur.
  • Cache errors in the processor; the cache stores important data and code. If this is corrupted, errors often occur.

Famous quotes containing the words problem and/or types:

    What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.
    Archibald MacLeish (1892–1982)

    If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.
    Henry David Thoreau (1817–1862)
