Northbridge hot on standby
 
Does this sound familiar to anyone? This is not on my PC, this is on a two week old 1150 motherboard that won't even get to bios post message. It turns on and immediately off again. The north bridge is running at 55C on standby - computer turned off. All peripherals removed. Only cools down when cpu is removed. cmos reset doesn't fix it.

Hi...

Interesting. I've not heard of this kind of issue before. What is the motherboard precisely and what OS is running on the system? At this point, it sounds like either a driver or motherboard/chip issue.

So, what's the part number of the motherboard? Is your processor new or have you salvaged it from somewhere else? What type and model is it?
From your description it sounds like the OS is irrelevant as you're not even getting the splash screen or POST messages.
I'm inclined to think that the CPU is faulty, the Motherboard won't POST if it is. The overheating north bridge also points to this:

This would back up this supposition,if possible, I'd definately try another CPU.

Play Bonny!

Hi...

Excellent point. I must have been thinking of something else when I wrote my last post. :o

By the way, what does "Play Bonny" mean in Scottish lingo?

Oskar: Disregard my last post, at least concerning the driver. ;)

@ ardvark71

"Play Bonny" translates as "Have Fun" in standard English. :D

So... Er... Play Bonny!

It's a GA-H97-HD3 with an i5-4690.
My first suspicion was that someone may have been monkeying around with the northbridge voltage and shorted some pins. But that wouldn't explain why it cools down when I remove the cpu. Some 20 yr old build it. Likelyhood of monkeying around rather high. Oh, and the cpu cooler wasn't seated correctly. I'll see if I can dig up an 1150 cpu somewhere and see if it's indeed the cpu.

Thank you, sir, I usually try! :D

Hi...

Let us know what you find out... :)

So I let it sit for about an hour without the cpu installed and it was still hot to the touch. Maybe the drop in temperature I measured was just a fluke, or maybe it just runs slightly hotter with the cpu installed. The owner vehemently denies having done any sort of tinkering with the voltages.
The cpu is new, unfortunately I don't have an 1150 lying around anywhere to test.
This one just goes back to the manufacturer as is. No idea what caused the problem. Thanks for the input everyone!

Hi...

You're welcome, it may have been just a bad motherboard, too. Can't tell for sure unless you were able to try another CPU that was known to work. :(
