EPU-4 Engine EAccessViolation on PC


EPU-4 Engine is an optional power-saving feature in certain motherboards made by ASUS. This feature has two components: hardware (physical part) and software (program suite). The error you're seeing appears when the motherboard gets changed to one that does not support EPU-4 Engine but the software is still active on the machine. The solution is to remove the associated software from your computer by doing the following:

1. Click "Start" and then click "Run"

2. Type in %ProgramFiles% and press Enter.

3. Your Program Files folder will open. In it, locate the folder named "ASUS AiSuite" and delete it.

4. Restart your computer.

The error will not appear anymore.
