3 days ago, my pc was running fine. I turned it on and it booted. It obviously didnt give me a signal because I didnt have a gpu or igpu. Then my graphics card (5070) came in 2 days ago. I turned off the pc, unplugged it put the gpu in the slot but then it only turned on for 1 second then turned off. Do you think its the motherboard or psu? I really dont know and I need this build finished now.
