At first, I doesn't display anything but after trying couple of times, I manage to go inside bios, and it was doing black screen on and off like crazy. After restarting couple of timeI manage to install windowns 10 without problem. Now, after I installed it, I restarted my pc once again. Now, it wont display anything.

I manage to show the asus logo and options the indicates to enter bios. but in a split seconds, it's gone. Now I can literally tell it has display because the screen is greyish and not black. It's kinda frozen or something. No matter what I do, it's doing the same.


I tried basic troubleshooting. I used my ram and gpu on different pc and it's working fine.
now i tried different ram and gpu on current build and it's still doing the same. I tried different processor and i7, still doing the same.

Does it have to do with the board? I just bought the board proc this morning in local shop brand new.


Any suggestions what to do? Last result is get a replacement
