Hi guys, I've been puzzling over the last month to solve this problem. In some moments (I noticed that this often happens during the downloads) I feel the PC fan (Asus ROG GL753VE) increase the speed considerably, I go on the management activity and I notice the "process" System Interrupt that for even less than a second occupies 100% of the CPU. Shortly afterwards everything returns to normal. In this period I made a format (but the problem persists) and various tests with Windows Performance Recorder and LatencyMon that have highlighted a high demand for DPC by the ntoskrnl.exe file.

Here the test result with LatencyMON (1 hour)

Would anyone know how to give me a hand?
