You have a high-end computer that is running Windows 7 or Windows Server 2008 R2. When the graphics processing unit (GPU) on the computer operates under heavy load conditions, you may receive the following Stop error message:

Stop 0x0000007E (parameter1, parameter2, parameter3, parameter4) SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

Notes

  • The parameters in this error message vary, depending on the configuration of the computer.

  • Not all the "Stop 0x0000007E" Stop errors are caused by this problem.

This problem only occurs when the GPU utilization is high.

Cause

This issue occurs because of a time-out issue within the GPU. This causes a reset that leaves the GPU in an inconsistent state
