Knackered motherboard? :)

bobert50 · 1 Apr 2018 at 14:57

I have a pc that after a house move is just refusing to power up at all. The specs are as follows:

Asus Z97 D3H mini ITX
Intel i5 (4670k)
8gb Ram
500watt PSU (But i've tried multiple different psu's to rule out psu).
Multiple pc cases have been tried just incase of an earth problem.

Basically you try to turn it on and literally nothing at all happens. I've tried 3 different corsair psu's with it and wired it up appropriately and even got a friend to wire it up incase i was somehow losing my mind! but same result.

If it can't be the PSU, I guess the motherboard is dead? Does anyone have any ideas? or anything worth trying? presumably it can't be the motherboard battery because it would still power up but just lose other info?

Like above, it doesnt even try to power up, you try to hit the power button and nothing happens at all, not a sound.

Any help very appreciated!

Try taking as much off the board as possible. 1 stick of RAM. See how it behaves with or without the GPU - does it beep without it?
Does your RAM/GPU work in another machine?

Try without the HDD/SSD. I've seen some short - i.e. positive and negative had a direct connection - not good.

You seem so happy about it lol

I suppose that’s because you now have a reason to upgrade, which we all like doing

Remove the CPU and reseat it - it may have dislodged slightly, LGA 1150 has no pins to hold it in place.

When you tried the different PSU's, did you use the the same power lead (from wall to PC)?

Thinking maybe the fuse has gone in the plug.

That's a good idea - I've tested fuses before but not found a 13A fuse blown yet in a computer.

It is possible it is the fuse, especially when power leads between monitors and pc's get switched around and people don't realise they are lower ampage.

Do the paper clip psu test (google it) and if the psu spins up you know it is not anything to do with the psu, plug fuse included.

Then take it all out of the pc case... rebuild outside of the case with minimum amount of things attached and try to turn it on.

try another power cable ?

You can get a power supply tester for ~£12 to check it's not the power supply.

I’d say it should be worth checking if there is something else up with it first before assuming the motherboard... unless you’re just looking for an excuse to upgrade lol

Try taking nearly everything out and trying rebuild could be something not seated right.

Have you tried starting it by shorting the jumpers on the board rather than case switch? Just in case thats faulty.....
