How to fix frame stutters in ELDEN RING caused by Huntkey Blizzard T620 Colorful?

Every time I activated a combat skill, the screen stuttered slightly, and this unpredictable delay was maddening. I tried replacing the power cable, but it caused a system reboot due to a loose connection, which was a clumsy mistake. I used GamePP System Backup & Config Export to identify and resolve power load balancing conflicts. AIDA64 confirmed voltage fluctuation converged to 0.01V from 0.05V, and the system stabilized, allowing for smooth combat execution without latency spikes.
