I paid £170 ($230) for this faulty gaming PC, but what’s wrong with it?

I recently won an auction for a Ryzen 7 gaming PC listed as faulty, but for under £200 or $250, I thought it was still worth buying. So what exactly is wrong, and can we fix it? 0:00 The PC 0:44 What's Inside? 1:43 Does It Switch On? 2:15 The Bios and Specs 3:05 The Issues Begin... 3:28 Disassembly 3:43 The PSU 4:08 Broken Wire... 4:27 The Graphics Card 4:49 Removing The CPU Cooler 5:05 THERMAL PASTE 6:59 Is It Fixed? 7:37 A Few Hours Later... 8:22 Gaming Tests / Counter Strike 2 9:05 ARC Raiders 10:00 Cyberpunk 2077 10:36 Fortnite 11:11 GTA 5 Enhanced 11:48 Kingdom Come Deliverance 2 12:25 Resident Evil Requiem 12:54 Starfield 13:30 Final Thoughts Thanks for watching :)
