My Pc has been working perfectly fine for the past two years. Today after dinner it just decided to not turn on. When i try turning it on the CPU light flashes for a quick second than the rest, DRAM, VGA and BOOT light flashes. This only happens once in awhile and I would have to unplug the power cable and replug for this to occur again. I really dont know what to do, please help. I have an MSI B350 motherboard.
