Question New PC build can't launch games without freezing/crashing ?

[richiepea]

I recently built a gaming PC for the first time using PC Part Picker.com. After piecing it together, I left the BIOS in optimized default mode and after installing Windows 11 it worked fine by loading Overwatch 2, Civ 6 and Terraria through Steam. I downloaded Helldivers 2 and Lethal Company, loaded Helldivers 2 and it froze during the opening cinematic. To get back to the desktop I had to alt-tab, right click quit, stop the program in Steam and then right click quit out of Steam to shut down Helldivers 2. I had to restart the PC to launch Steam again. Lethal Company loads into the Unity logo and freezes then stops responding. Civ 6 freezes after loading from Steam.

I updated all the drivers, reinstalled Windows, Memory Diagnostics, etc. Mostly all Googled tips and tricks as I'm new to this and I'm desperate at this point for a solution. Can someone help?

latest bios?
ram running at docp/xmp profile?
check cpu temp?

6800 with a midrange 550W PSU is a bit of a stretch... Is it daisy chained on top of that?

XFX recommends a 750W PSU for the card and that's the general consensus for a Radeon 6800.
