ASUS ROG Strix GL12CM repairs and upgrades
Power supply repair
Random restarts under load and a PC that will not start are often the power supply. We test it and fit a quality replacement of the right capacity.
Graphics repair
We diagnose and replace failed graphics cards, and check that the power supply and case can take the card you want before an upgrade.
SSD and storage upgrade
The ASUS ROG Strix GL12CM has room for SATA drives and, on most boards, an M.2 SSD. The usual upgrade is an SSD for Windows and programs with the old drive kept for storage.
Price confirmed before work starts
Memory upgrade
The ASUS ROG Strix GL12CM uses standard desktop memory. We check the board’s limits and fit matched modules.
Overheating and fan repair
We clear dust from heatsinks, fans and filters, replace failed fans and renew thermal compound. On liquid-cooled systems we test the pump.
Windows repair and reinstall
The ASUS ROG Strix GL12CM meets Microsoft’s Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
We also carry out motherboard repair, virus removal on the ASUS ROG Strix GL12CM, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
What we see on the bench
- Overheating is usually dust, a failed fan or a liquid cooler pump at the end of its life.
- A PC that powers on with no picture is more often memory, graphics card or power supply than a dead motherboard.
- Gaming desktops from the big brands mix standard parts with some brand-specific motherboards, cases and power supplies, so upgrades are checked against the chassis first.

Questions
Can the SSD or memory in the ASUS ROG Strix GL12CM be upgraded?
Drives can be added or replaced. Memory uses standard slots and can be increased.
My ASUS ROG Strix GL12CM will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
Is a 2018 ASUS ROG Strix GL12CM still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
Where do I find the model number on my gaming desktop?
The model is on a label on the back, side or underside of the machine. For this model, look for GL12CM.
