    Question Desktop starts to turn on, then red CPU light and turns off again. Cycles repeatedly ?

Out of the blue when I tried to turn it on this morning, the blue fan light turns on, then after about a second, a red CPU light appears on the motherboard and it turns off again. It continues trying to turn itself...

    Question Build won't POST, how to verify it's the CPU

    I have two homebuilt computers that we use in my lab that stopped working. First they occasionally blue-screened, but then got to where they wouldn’t even POST. This happened about a year apart at the same station. I later learned that there was a faulty UPS there backing up the PC power...

    so I have a b450 tomahawk paired with a 3700x I don't know the percentage but there is always a chance that when I try to turn on the PC the cpu light stays on and wont boot. so I cut the power then try again then the PC boots up normally. sometimes the cpu light could stay up two times in a...
