I've built my system about a year ago and everything worked fine until yesterday. My pc showed no display, and vga led came up on the motherboard. Case, gpu and cpu fans run normally. Also i think it boots to windows as I've heard the usb plug/uplug sound while connecting my monitor.
My specs;
Windows 10 64 bit standart
Gigabyte x570 aorus ultra with f30 bios
Amd Ryzen 3700x
2x16 gskill trident z neo 3600 mhz ram
MSI gaming trio RTX 2080 super
Samsung 860 evo ssd as the boot drive
Corsair TX 750m power supply
Dark rock pro 4 CPU cooler
Cooler Master h500m case
Possible trouble shooting I've tried with no avail;
Tried HDMI cabble instead of display port
Tried a different monitor, also tried both connected at the same time
Tried my current monitor on my old system and it works
Removed power and CMOS battery
Qflashed to an older BIOS (F22)
Checked all the power connections, tried new cables for gpu
Tried each ram in every ram slot alone
Tried my old GPU (sapphire rx 590)
Tried different PCIE slots
Tried my current psu in my old system with the rx 590 and it works. (can't try it with 2080 because it would not fit the case)
Disconnected all sata and usb connections
Also checked the CPU for bent pins but I did not see one
Bought a new motherboard (Asus Prime B550M-K) as I've thought it was a faulty PCIE controller or something, still no display.
So at this point I'm thinking about buying a new cpu as i think I've tried every other component, but I don't want to waste any more money so I thought i would ask for your oppinion. It is weird that if the cpu is broken it can still boot to windows.
Thanks a lot for your help.
