I built my PC last November, and it was running smoothly until recently. Now, it's been crashing while playing both light and more demanding games. For instance, when I play Madden 26, I can play for about 20 minutes without any issues, but then the PC starts lagging and crashes shortly after. Sometimes it shuts down completely, and other times it just crashes the game itself. I've also experienced a black screen that flashed an error code (0xc000021a). I've got the following specs: a Gigabyte Aero G b650 motherboard, a 7800xt GPU, an AMD Ryzen 5 7600X processor, 2 sticks of DDR5 RAM, a 750W Thermaltake PSU, plus one 1TB SSD and another 2TB SSD that isn't functioning properly anymore—I think the new one might be failing. Anyone have any suggestions on how to fix these issues?

Have you tried updating your BIOS? Also, make sure your AMD chipset drivers are up to date. You can check for driver updates with the Gigabyte Control Center. It might help stabilize your system.

I updated the BIOS last month, but the website only has an older version available, which I already installed.
