PC Not Booting. Power Button Flashing On Motherboard?

Last response: in Systems

So, I just got home and wanted to get on my computer like usual. Now I tried to turn it on and realise it wasn't booting. In fact, no power was turning on. I decided to check the power at the back to make sure everything is on, which it was. This is where I panicked a little.

I opened up my computer and I noticed the power button on the motherboard flashing. I tried pressing it and it refused to do anything. So, I did some searches on the internet to check what was going on (I used another computer to check). It suggested that it might be the PSU. Now, I've tried the paperclip test and the PSU fan turned on. So, now I'm not sure what to do. I've even unplugged some of the hardware to see if there were the causes. But nope, nothing seems to help...

Any suggestions on what I can do?

I have a Gigabyte Z87X-UD3H motherboard. And I have a Corsair HX650W PSU.

EDIT: I'm a little worried if it is my mobo, because I only got this last month and it was working fine and all until today. My mother said that she turned off the main power this morning and there was some thunderstorm earlier too. Could that have some causes?

I'll suggest resetting your CMOS here as a first step.

I suggest trying the paperclip again. This time connect one or two fans to the PSU molex connectors and check if spinning.

I've already done that last night. If it's just pressing that button on top of that power button that is?

OK, I'll have to try that later.

With the PSU unplugged, remove the battery from the motherboard for 15 seconds then put it back in. That will reset your CMOS clock (and BIOS), see if anything then

Alright, I just did the test again with 3 fans and all of them were running.

Took the battery out for like about 5 minutes. Placed it back in and it's still the same. :/

If starting the board with only CPU and CPU fan installed, same led flashing? If yes, then it might be a board issue.

I'll check it out soon. But if it is the board issue, what can I do? Do I have to get a new one...?

Since under warranty, you can RMA-it.

Well, I plugged everything out of my motherboard leaving just the CPU and CPU fan. The LED is still flashing... So that pretty much confirms it's the board?

Check http://www.tomshardware.co.uk/forum/226397-30-blinking-...
If nothing works, yes, motherboard or power supply.

Sorry to reply this late, but it's finally fixed today. It was definitely the PSU. One of the capacitors blew up inside.


Now that is something I would not expect from an HX model. I wouldn't expect any recurrences.

Yeah, even the guys at the store were surprised about it. I've had this thing for at least 4 years, and going through so many thunderstorms in the past, this is the first time it has ever happened (and for me to even see such a thing to happen). Which is pretty bizarre.
