Beta 5 repaired many issues. Thank you.


Now, when I restart the computer (every time) I get a black screen with a white distorted field (shaped in a large L) with red, blue, yellow and green white noise. Computer restarts without any issues once it gets past that screen noise. Specs below.

I have the same trouble. my investigation is the following one : due to the fact this video chipset heat a lot and the fan is not suffisent to cool it enough, the thermic paste become more and more insufficient and destroyed the chipset. you must change the mainboard
