Hello,

So I recently upgraded some components in my system, and also did a clean reinstall of Windows. The issue now is, everytime my monitor goes to sleep (PC just idles), it wakes up randomly after a small amount of time, and back to sleep again. This repeats over and over while it’s idling.

I have tried to unplug every USB and other peripherals and it still happens. Closed out many applications that runs as services in the background as well, and it still happens. Even before logging in at fresh reboot it happens. Even changed from displayport to hdmi, taken out graphics card and use internal graphics, and also happens.

Does anyone have an idea what can cause this? I’ve used the windows diagnostic tool to check Dstate, but nothing out of the ordinary except it just shows as waking up, but not by what, and nothing else around the same time that would cause a wakeup.
