Hi,
I took my pc into my local repair shop as it was not booting it was freezing on the Asus screen with the red led boot device on. This was still happening with everything disconnected and only a single ram stick so I came to the conclusion it's the Motherboard. Just for clarification I decided to take it to the repair shop and they confirmed this. But when I went to collect it from the repair shop they said the power button is no longer working and the repair guy was having to use a screwdriver across the contacts on motherboard to power it up.
I thought that was odd as there was no issues with the power button when I dropped it off at the repair shop.
Having been confirmed the motherboard was faulty I thought maybe that also caused the power button to stop working so I got me a replacement motherboard.
The replacement board has resolved the booting issue and it now boots up fine and loads Windows however the front pc case power button does not work still and the only way to power it up is by pressing the reset button on front of pc case.
What has the repair guy done to this front panel power button for it not to work could he have put the power button and reset button on the wrong pins and is it safe for me to swap them around to try to see if this will correct it?
Sorry for long post and hope someone can help me out.
Thanks
 
If you look on the cables from the front panel that go to the motherboard they will say what they are.

If it was working when it went to the shop then its something they have done and should fix it as it was fine when you dropped it off.

What case and motherboard do you have?

The guy who worked on it told me he had to call the shop owner for advice as he was just filling in while the owner was off which didn't give me to much confidence.
I went to the repair shop two days later after I had the replacement motherboard fitted to ask him to fix this issue he caused but there was a sign on the window saying closed until further notice.
The lettering on the wires are corresponding to the letterings on the block pin that fits on the motherboard so wondering if maybe they were written on wrong originally and it's just a case of changing the power wire onto the reset pin and power reset onto power pin.
Will this do any damage?

I would assume that the reset swich and power button are the same. When pressed it sends a signal to the pins on the board to either restart the PC or turn it off.

Can you post any pictures of the wires to the motherboard at all?

I have taken photos of the wires connected from power switch on pc case to power block that fits onto the motherboard but not sure how to upload them on here?

You will need to use a hosting site as you cannot upload them directly to the forum.

This is my work pc so components are old but it has been working for years without issues and does the job so there was never any need to update it and is why I stuck to the same board when I replaced it last week due to needing to get it up and running ASAP and not having to buy all new hardware.
Asus P8Z77-V PRO Motherboard
Akasa Mirage-62 PC case.

Are you able to trace the power button cables and reset button cables?

Are the power power button cables connected to anything at all?

Tried looking for a manual on the case but not much about, got the Front Panel details of the motherboard fine
 
Photos are showing one side of the power connection block with three pairs of wires connected red/white H.D.D. LED, orange white PWR Ground, blue white Reset Ground
Other side of power connection block with one pair of wires connected green white +5V Ground
The other photo shows my pc front case power buttons.

Thanks, Have you tried the cables directly in to the motherboard without the white adaptor?

Int he 2nd picture there is a green and white cable connected to 2 out of the 4 speaker pins (Ground and 5V), what are these for?

Hi, no I have not tried connecting wires directly to Motherboard without white adaptor so maybe worth me trying. The (Ground and 5V) green white not sure what those are for if I am honest.
 
If I swop around the orange white PWR Ground, blue white Reset Ground to see if that may correct it can it cause any damage to the Motherboard?

Maybe those green white cables (Ground and 5V) are to do with these inputs on side of case near the power buttons?

They would normally go to headers on the motherboard directly.

You can give that a try, looking at the picture they are setup correctly and not swapped over which the shop said they had to do (used the reset switch for power as the power button did not work)

The shop never tried the reset switch when he caused this problem he showed me powering it up in the shop by using the screwdriver method without any cables on the motherboard. It was me who found out the reset button powered it on.

Wonder if the green and white wires are for the power LED?

A speaker usualy uses the outer pins (Speaker and +5V).

Maybe the wires have detached from the power button itself.

Diagram from the manual.

This guy explains all the connectors in detail.

I would first try without the white block in-between the cables and motherboard and then connect them directly to the board as it could be that causing the problems.
