It is stuck in a black screen at times, with the power button & reset not making it respond aswell. It sometimes would power up but not boot.
Sometimes it also would show some coloured dots all over the screen. Now, it sometimes boots till bios, allows me to navigate through bios, sometimes also boots windows & sometimes doesn't even power ON.
Have so far done an overnight RAM test which it has done multiple passes. Also the PSU seems fine. If I pull out RAM and boot it boots and does the beeps, but if I pull out GPU it boots with no beeps.
I didn't find the right solution from the Internet.
