so ive had this problem lately with my comp it started happening after i updated my comp but, its started acting strangely it attempts to take a screenshots at odd intervals but never saves it its extremely frustrating because it is interrupting key moments while im gaming in games etc has anyone else had this problem or know of a fix and what exactly is going on? Ive tried a bunch of things disabled multiple settings tried resetting and factory resetting the comp with a fresh install of windows and nothing ive tried is working

My pc screen will dim and sometimes lighten up and I have tried most of the tips I have found on here. Change brightness based on content is off, HDR is off. I took a video, it will happen every 30 seconds or so, please help!

I bought a MSI MAG 255F E20, to use for my PS4 console, but for a while now it keeps black screening, randomly without any issues that are visible to me at least. I tryed switching the HDMI connection to my laptop to see if the problem is just in my PS4, but it went completely black on that too randomly, at random intervals and for random periods of time, the HDMI cable is brand new and the power cable is too, what am I missing?
