I recently built my computer a couple months ago and been having graphic related issues since the very first day, though asking on forums I still couldn’t find the cause of the problem. After spending more time using my pc more symptoms have occurred which I will list all below:
(1) Both onboard gpu and dedicated gpu are having graphic issues where in every game certain texture, objects and lighting will flash, flicker and move. Shadows will morph and have some weird blur and pixelated tear. This is not game related either.
(2) Also while gaming I will notice intermittent micro-stutter or hitch. Some players look jittery when moving too.
(3) During gaming in CSGO I tried to turn my monitor off and on for fun. Upon turning it on it makes a disconnect/connect sound, then my screen will have a black spot with pixelated visuals. I cannot move in game also. The only way to get everything back to normal is to alt-tab out. I have also included a picture.
(4) I also did a UFO Test and during the test at the top of the screen there is flashing, flickering and little pixelation. This is not a monitor or display port cable issue either.
(5) Another weird thing I noticed during boot up if I don’t switch my monitor on first before switching my computer on. I will get a red light for vga on my motherboard led. The light will continue to stay on but I can still boot fine.
(6) There was also a day when my graphics card had 3 red led lights flashing. But I was able to boot still. This continued for a day or two but now stopped.

If I had to guess what is wrong I would say it’s either Asus drivers or motherboard. Hopefully I can find out soon with the help of this community as this has been bugging me ever since the first day I built this pc.*
Thanks.
