Why Did This PC Need a Motherboard Replacement?
The customer brought the PC into our shop because the motherboard ports had stopped working. The AIO cooler pump had also failed, so the system needed more than a simple clean or software update.
For this repair, the customer wanted the issue sorted properly: replace the motherboard, switch from AIO liquid cooling to air cooling, and deep clean the whole PC while the system was already apart.
Root Cause
The motherboard ports had failed, and the AIO cooler pump was no longer working. We replaced the motherboard with an ASUS ROG Strix B550-F Gaming Wi-Fi 6 and Bluetooth board, replaced the failed AIO with a Thermalright Peerless Assassin 120 SE Black air cooler, deep cleaned the PC, updated the drivers, and stress tested the system.
What We Checked First
- Confirmed the motherboard ports were no longer working properly
- Confirmed the AIO cooler pump had failed
- Checked the customer’s requested repair direction: new motherboard, air cooler replacement, and deep clean
- Prepared the system for full disassembly, cleaning, rebuild, driver update, and stress test
How We Fixed It
- Full disassembly: We dismantled the PC so the motherboard, cooler, case interior, fans, and hidden dust areas could be properly accessed.
- Deep clean: Dust was cleared from the case, components, fan areas, heatsink areas, and other internal sections while the system was already apart.
- New motherboard: The failed motherboard was replaced with an ASUS ROG Strix B550-F Gaming Wi-Fi 6 and Bluetooth motherboard.
- New air cooler: The failed AIO cooler was removed and replaced with a Thermalright Peerless Assassin 120 SE Black air cooler.
- Driver update: After the rebuild, we updated the drivers for the new motherboard setup.
- Stress test: We stress tested the PC after the rebuild to confirm the system was stable and ready for return.

Dust Build-Up Before Cleaning
The PC came in with visible dust build-up, so we carried out a full deep clean while the system was already being repaired.
System Disassembled
We dismantled the PC to access the motherboard, cooler, internal case areas, fans, and hidden dust spots properly.
Deep Clean
With the PC fully disassembled, dust was cleared from the main internal surfaces and hard-to-reach areas.
New Board and Air Cooler
The failed motherboard and AIO cooler were replaced with an ASUS ROG Strix B550-F board and Thermalright Peerless Assassin 120 SE air cooler.
Stress Tested and Ready
After rebuilding the PC and updating the drivers, we stress tested the system to confirm it was stable before return.
"When a PC comes in with failed motherboard ports and a dead AIO pump, we do not just replace parts and call it done. Since the system is already apart, it is the right time to clean it properly, rebuild it neatly, update the drivers, and stress test everything before returning it."
Mansa ComputersFinal Result
The PC was rebuilt with a new ASUS ROG Strix B550-F Gaming Wi-Fi 6 and Bluetooth motherboard and a Thermalright Peerless Assassin 120 SE Black air cooler. The failed AIO was removed, the system was deep cleaned, and the drivers were updated.
After the rebuild, we stress tested the PC to confirm it was stable and ready to return to the customer.
