So I built this PC around two months ago, everything seemed fine but yesterday when I tried turning on my PC everything that was connected to the mobo isn't working but every fan and Led that is connected to my PSU works, I tried removing all cables and reinstalling, switch ram sticks, trying ram one at a time, clearing CMOS nothing seems to work.. it once or twice randomly started working again but after an hour of use it goes back to the way it is.. the motherboard has a small red led beside the where it says "CPU" indicating that there is an error with the CPU but I still can't be sure whether it's the cpu or mobo.. I don't have another system to test this on, what should I do send both the cpu and mobo or is there a way to identify whether it's the cpu or mobo
Motherboard: H110i PRO AC
CPU: i5 6500
PSU: EVGA supernova 550 G2
(everything is less then two months old)
