CPU symptoms

Symptom : The system boots with no problem, but crashes or freezes when certain applications are run. It may appear that the application is corrupt.
  • Test the CPU. Try a diagnostic such as TouchStone Software's checkIt. Run repeatitive tests on the CPU. While the CPU may work in real mode, diagnostics can detect errors running protected-mode instructions and perform through register checking.
  • Replace the CPU. When an error code suggesting a CPU fault is returned, try a known-good CPU.
  • Expand the diagnostic. If a CPU fault is not detected, expand the diagnostic to test other portions of the motherboard. If the entire system checks properly, you may indeed have a corrupt file in your application.
