You'll need your motherboard manufacturer's manual to interpret these as they are not always the same with different boards

3)Case / PSU / GPU / CPU fans. Most people already covered this one. Especially if it's loud and not preventing the computer from booting, this is very likely.
1)if hard drive issue, you'll get an error after post...
2)i know on asus and msi boards a load buzz happens when i dont mount the ram correctly...
3)computer can post without fans...
