**Hardware: ASUS H81M-K**
**Issue: No Display Upon Power On**
**Steps Taken for Troubleshooting: BIOS Flash to Latest and Lowest Version, Resistance to Ground Checked for Short Circuits**
**Explanation:** The ASUS H81M-K motherboard exhibits a peculiar issue where the system powers on, but no display is observed on the monitor. The symptoms include the motherboard receiving power and the power supply unit's fan spinning, along with the CPU fan if the power outlet is connected.
In an attempt to resolve this problem, the following steps were undertaken:
1. **BIOS Update:** A BIOS update was performed, applying both the latest and the lowest available versions. However, this did not rectify the issue.
2. **Resistance Check:** A thorough examination was conducted to check for short circuits by measuring the resistance to ground. No anomalies were detected during this assessment, suggesting that the motherboard was free from shorted or low-resistance pathways.
Further attempts were made to isolate the problem:
- **RAM and CPU Test:** The RAM and CPU were removed from the motherboard, and the system was powered on without these components. Despite their absence, the power supply continued to turn on automatically.
- **CPU and RAM Test on a Different Board:** To verify the integrity of the CPU and RAM, they were tested on a separate, functioning motherboard, where they operated without issues.
The aforementioned troubleshooting steps have not yielded a resolution to the problem. Therefore, any insights or guidance from individuals with experience in similar scenarios would be greatly appreciated.
