i built a computer about one week ago, and it was working perfectly for a couple days. then, one night for no reason whatsoever, it stopped booting. i didn't know what was wrong, so i went through and tried resetting/reseating/replugging in everything (seriously, i went through both entire troubleshooting posts on here, as well as checked through buildapc. nothing worked, so i bought an onboard speaker to hear post beeps, and i get the 5 beep error message. I've narrowed it down to it either bing my cpu is dead, or my mobo is just not recognizing it anymore. I'm considering taking it in to a repair shop to have them swap parts out and check that way, but is there any other way you guys know of to try check which might be broken? other than the CPU socket, i've already checked that and there are no bent pins or anything. heres my reddit post, with pictures of the socket, and the specific build parts.
