Check if your i5-9400 CPU fits the motherboard you're using.
Hi, I have an i5-9400 and think it uses the LGA1151 socket. I was browsing Ebay looking for motherboards with "LGA1151" in the title, but none of them passed the PC parts compatibility check. I checked several PC builder sites from Google, but they didn’t match. Here are the boards I’m thinking about: ASUS H170M-PLUS, GIGABYTE GA-H110M-S2H, and ASRock Q77M VPRO. My RAM is DDR4 at 2666 MHz with 24GB across two slots. Let me know if any of these fit.
