Pc Boot looping :(

[Sleepy_gamer_boi]

A pc I built a while ago started to have issue's today, when it was turned on it would just boot loop, i checked the little debug screen on the motherboard and it gave me the error 03, i checked the manual and it said it was something wrong with the Power on North Bridge Initialization, i wasn't quite sure what that meant i needed to do and after a little bit of googling it seemed like i needed to try reseating the cpu, gpu, and ram, so i tried that and while i was at it i reseated the cmos battery but did not replace it and i did the unplug and replug on all the cables, but after i did that i continued to have the boot loop that ends with the debug light on 03 so at this point I'm not super sure what to do. If you guys know anything i could try to get it working I'd definitely appreciate it!

POST code 03 = System Agent initialization before microcode loaded.

In short your CPU is trying to startup and did not seem to finish.

 

Best thing to do typically for failing to POST is min config.

Turn system off and start with removing 1 RAM stick. Turn back on and keep going one part at a time until it changes. Make sure to try each RAM stick in the main slot to rule out a bad slot on the MB. 
If you have a spare CPU try that, but I fear this CPU is dying.
