Stop 0x0000007F or UNEXPECTED_KERNEL_MODE_TRAP

Causes : 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.

Solutions:

• Run any system diagnostics that are supplied by your computer manufacturer, especially a RAM check.

• Running the CPU beyond the rated specification, known as "overclocking," can cause Stop 0x7F or other error messages due to heat buildup. When diagnosing problems on overclocked systems, first restore all clock and bus speed settings to the manufacturer recommended values to determine if this resolves the issues.

• Use the Windows XP System Restore feature is system boots into SAFE MODE.

• If all Hardware fully functional reinstall Operating System.
