One day I was peacefully playing minecraft. I was using medium-ish settings so my pc must not have been under too much load. I was getting around 245 FPS then suddenly my computer freezes. For about 2 minutes I wait there hoping it is some momentarily lag spike, but it stayed frozen. Next I tried rebooting but now I was getting a no-post. I tried removing ram with no luck. I wasn’t getting any beep code. I tried resetting the bios but that didn’t work either. All my fans are spinning. Please tell me how to properly diagnose what is wrong with my PC.
