| | Likely Cause & Solution | |-------------|------------------------------| | No display after power-on | Incompatible or improperly seated RAM. Try using a single known-good 2GB double-sided module in the first DIMM slot. Some 4GB modules may not be recognized. | | PC turns on automatically when plugged in | A BIOS setting related to "Wake on LAN" or "Power on by RTC" may be enabled. Check the Power Management section in the BIOS. | | Front panel USB / Audio not working | Incorrect header connections. Verify the case cables are plugged into the correct headers (F_USB1, F_AUDIO) with the correct orientation. | | System unstable or random crashes | Could be overheating (check CPU cooler), faulty RAM (run MemTest86), or a failing power supply. | | "No bootable device" message | Incorrect boot order in BIOS, or a failed hard drive/SSD. Also check SATA data/power cables. |
A: It is very unlikely. The Acer MG43M uses an OEM motherboard not designed for enthusiast overclocking. The BIOS likely has very few, if any, options to adjust voltages or CPU multipliers.
When configuring or restoring a machine built around the MG43M, finding verified technical schematics can sometimes prove challenging due to the crossover nature of OEM hardware. Since this board was developed by MSI specifically for Acer's enterprise lineups, technical assets can be obtained via distinct routes.
