I'm having a power and reset button issue

[navem]

Hey everyone... first time poster here. Have trusted the posts on this forum for a long time so I thought I'd post my problem here...

I'm having a power and reset button issue.

This is what i exactly do to start the system: Turn it off from the power supply, press the power or reset button on the tower, then turn the power supply on. This seems to work on couple of tries. Weird thing is that the external hard drives connected to the system are getting their power, while the system itself shows no life...

It's a custom build desktop, with core i7 5930k, GTX 980 Ti, 32 gb ram. The power supply is 1000W, so it's more than enough. I've had a bad history with this build from the start. Ram config caused boot loop in the first week, then a couple of months later the motherboard went bad and would shut down after about 10 minutes and was replaced, and now I have an unresponsive power button...

Any similar stories, ideas or suggestions would be highly appreciated.

EDIT: Forgot to mention the motherboard - Gigabyte X99 Gaming 5P

if i am correct there is a cable going from ur case to the mobo u might want to have a look there.
on my previous pc i had an issue like this but in my case it was the button so u might want to take that apart aswell you should be able to use the plain switch without the fancy cap on it but it might work

If devices connected to USB port are getting supplied that means the 5V SB (standby) power is running. That's the power your motherboard uses to fire up when you press the power button.

From your description, seems like wiring or front panel problem. Open the case and (very carefully) remove the power switch cable, then short-circuit the 2 pins on the motherboard with some metallic object (i'd suggest a small flathead screwdriver) - avoid touching anything else or you could "fry" the motherboard. Sorry i can't post a picture but you forgot to mention the motherboard model.

Edit:
here's a picture of motherboard with power connector that you can unplug and use a screwdriver to switch your PC on (presuming the wiring/front panel/switch are to blame). Please be careful when doing it.

Thanks for your reply.. and sorry about that... It's a Gigabyte X99 Gaming 5P motherboard. I did try switching the power and reset wires (similar to the image) to see if the wires had an issue, but that didn't do anything. Haven't tried shorting it yet, but based on your reply, I might give that a shot...

Thanks for your reply... But, how will I know if shorting worked if I unplug the power cable? I'm not clear on what shorting will do exactly... Does it short using the current from the 5V battery? and does it fix the problem or only reveal the issue and I would still have to get the wiring fixed?

When u are changing the cables unplug the PC and ground urself to ensure no short circuit

Hey holyprof. I tried this today. No dice. Nothing happened! I get the feeling that something should happen, so I'm guessing I did something wrong. My screwdriver is metal though. Should conduct.

Sad to hear that your problem persists, but can't help you with words anymore. Find someone that knows about PCs and/or electronics that can check what's going on using the right tools and measuring equipment.
