Why Us?
​
We understand completely how your gaming PC downtime could totally ruin your day.  When your gaming PC fails, it feels like the end of the world. Whether your system is crashing during intense firefights, hitting a Blue Screen of Death (BSOD), running dangerously hot, spontaneously restarting or refusing to power on at all, guessing which component is causing the issue could not only be time consuming and very costly, trying different random parts, you could also break those parts in the process.  The whole thing could turn into an even different kind of nightmare altogether!

At Complete PC & Mac Services, we have over 31 years of hardware experience, diagnosing and repairing custom-built gaming rigs, liquid-cooled setups, and high-end pre-builds, (we have routinely worked with Corsair, MSI, Alienware, Lenovo Legion, Acer, HP Omen, Gigabyte and ASUS ROG).  Don't guess what's wrong—let us come and diagnose it for you.
