If your CPU cooler does not have pre-applied thermal paste, place a small, pea-sized drop of thermal compound directly in the center of the CPU integrated heat spreader (IHS).
Secure the AMD retention bracket hooks to the plastic motherboard tabs and flip the cam lever to lock it. Plug the cooler wire into CPU_FAN .
Safety is equally critical. The installer must ensure they are working in a static-free environment. Grounding oneself by touching a metal object or using an anti-static wrist strap prevents electrostatic discharge (ESD) from damaging the sensitive circuits on the AAHD3VC. Gather the necessary tools: a Phillips-head screwdriver, thermal paste (if reinstalling the CPU cooler), and a bright light source to read the small text on the motherboard PCB (Printed Circuit Board).
Align the motherboard’s rear I/O shield with the cutout at the back of your computer case. Push it firmly from the inside of the case until it clicks into place. Step 2: Set the Standoffs
Apply a pea-sized drop to the center of the CPU integrated heat spreader (IHS) if your cooler does not have pre-applied paste.

Connects to the two leftmost pins on the top row. (Ensure positive [+] is on the left and negative [-] is on the right).
The is a Micro-ATX motherboard commonly found in pre-built systems like the Acer Aspire TC-105 . Because it is an Original Equipment Manufacturer (OEM) part, a dedicated retail "manual" is not publicly distributed; instead, technical details are found in service guides or community documentation. 1. Hardware Specifications
Pro tip: If your case uses a standard 9-pin block, use a multimeter in continuity mode to map the traces, or refer to our pinout diagram below.
Located on the bottom left corner near the audio chip. Connects your front headphone and microphone jacks. 5. First Boot and Troubleshooting
Locate the long 24-pin power connector on the right edge of the board. Plug the thick 24-pin cable from your power supply into it until the plastic clip locks. If your CPU cooler does not have pre-applied
Connect the 24-pin ATX power cable to the right edge of the board.
Push the metal I/O shield firmly into the rectangular slot at the back of the case from the inside out until it clicks into place. 3. Core Component Installation (Out-of-Case)

If you are replacing the board, remove the old one. Install the new or existing I/O shield (the metal plate for rear ports) into the back of your computer case. Ensure the motherboard standoffs are installed in the correct positions for a Micro-ATX form factor.
Once the core components are secured, it is time to move the board into your chassis. Safety is equally critical
Understanding the hardware limits is the first step before installation or upgrades. : Socket FM2 .
The most challenging aspect of installing a proprietary motherboard like the AAHD3VC is connecting the front panel headers. Retail motherboards have standardized pins for the power switch, reset switch, HDD LED, and power LED. However, OEM boards like this Acer model often use a specialized, consolidated block connector, or the pin layout may be non-standard.
Located on the right edge of the board. This powers the main chipset and logic.
Plug the 4-pin square power connector into the header near the CPU socket. The system will not boot without this. Peripherals and Audio
