I'm really frustrated because my new PC build has been giving me constant issues. Everything was working fine last night, but today I decided to replace my old GPU with a used Red Devil 5700XT. When I plugged it in, my PC wouldn't start up. The RGB lights turned on and the fans were spinning, but there was no signal on the screen (I was plugged into the motherboard). I noticed the DRAM, VGA, and CPU lights were blinking in a pattern, but none were solid. My build includes a Gigabyte Gaming X AX V2 motherboard, a Ryzen 7 7700X processor, a Thermalright Assassin cooler, and one 8 GB stick of Teamgroup RAM (the other stick is faulty). I was using an MSI Armor Tech RX 570 before the swap. Now nothing works, and I'm going to bed super mad!

Have you tried putting the RX 570 back in? Sometimes swapping components can cause more issues. It might be worth it to test that out to see if the system boots again.

I didn’t try that yet. I thought without a GPU it wouldn’t work at all, so I skipped it. I'll give it a shot now.
