| Symptom | Likely Cause(s) & Repair Steps | | :--- | :--- | | | 1. PSU Failure : Test with a known-good power supply. 2. Short Circuit : Check the 4-pin CPU and 24-pin ATX power connectors for shorts to ground. 3. Dead PCH (unlikely): If all voltages and clocks are present but still no POST, the PCH may be faulty. | | Continuous Beeping / Memory Error | 1. RAM Fault : Reseat RAM modules or test with one stick at a time in different slots. 2. Dirty DIMM Slots : Clean the slots with compressed air. 3. Incompatible or faulty RAM module. | | No Display / No GPU Output | 1. Dirty PCIe Slot : Clean the slot. 2. Power Supply Limitations : Ensure the PSU is sufficient for the GPU. 3. Check that the CMOS has been cleared after installing a new GPU. | | LAN Not Working / Dropping Connection | 1. Driver Issue : Reinstall the Realtek RTL8111G driver. 2. Check the LAN port for physical damage. 3. Chip Failure : The LAN controller can sometimes fail; a dedicated network card would be a workaround. |
