Hi guys, I recently build my own pc. Not long after my build my pc started flashing and flickering when I'm on chrome or leave it idle. During my gaming time, I didn't get any flickering issues. If I were to alt-tab to other windows it started flickering, and when I change back to my game nothing seem wrong. My connection doesn't seem to be the problem as I have tried using as a secondary display for my laptop.
I'm currently using :-
OS: Window 10 Pro
GPU: Currently don't have any (using iGpu instead Intel HD 630)
Connections for minitor : VGA to HDMI
Feel free to ask any other info you need. Your help is really needed as it's quite annoying to see when it flickers. Thanks in advance
