Boot failures are annoying. After swapping CPUs across three different boards, I picked up a few lessons that most build guides skip entirely.
Socket compatibility is the obvious first checkpoint. But the trap that catches most builders is BIOS version support. Your board might technically list your CPU as compatible, yet if the firmware is outdated, it won't POST. Check the manufacturer's CPU support page and cross-reference the minimum required BIOS version before you buy. Some retailers will flash it on request, but don't count on that.
Power delivery is where budget boards quietly fail. VRM quality gets cut on cheaper models, and at stock speeds, you might never notice. Push sustained loads or mild overclocks, and throttling shows up fast. Before committing to a board, look at the phase count and check whether the VRMs actually have heatsink coverage. This matters especially with higher TDP chips.
Cooler mounting deserves more attention than most people give it. Uneven pressure creates hotspots that no thermal paste will fix. Follow the mounting sequence in your manual, step by step. Skipping that is a bad idea.
One last thing worth flagging: RAM compatibility. Even kits listed on the QVL sometimes boot at base JEDEC speeds by default. XMP needs manual enabling in BIOS, and honestly, that's the detail most people miss. Miss it, and you're leaving real performance on the table without realizing it.
What I'd tell anyone starting a fresh build: check your BIOS version before the parts even arrive.
