New Build on PC, BOOT Red LED on ASRock B550M Pro4
CPU: AMD Ryzen 7 5700x
GPU: Gigabyte Windforce RTX 5060
PSU: Corsair RMe Series RM650e 650W
RAM: 16x2 DDR4 Ram Kingston Fury Beast
SSD: Gigabyte 500gb SATA
HDD: 1TB (I forgot the brand)
MOBO: ASRock B550M Pro4
The issue:
I was playing roblox while in a discord call and PC decided to blackscreen but fans and LEDs were still running. I only got to use the PC for less than a week. Hours prior to the blackscreen, my C drive became filled to the brim because I had viber installed on it, and my SSD was partitioned. Only the SSD and PSU were the secondhand parts here. I used the SSD on my old rig.
What I have done:
I've reseated multiple components, replaced the CPU with my Ryzen 3, swapped my GPU to a brand new exact same one, tried using windows installation media via USB while SSD is unplugged (still no signal on monitor), changed the order of ramsticks and even tried using only one. I've took it to a technician and he says he's tried all possible troubleshooting, and it still doesn't work. Also tried doing switching between HDMI and displayport, nothing seems to work, and I'm getting frustrated.
I really need the internet's help on this, thank you guys in advance for your help.
