custom built PC isn't turning on after shut down

[lightc]

Hi guys,

I have an interesting problem with my custom built computer. It all went well for 2 months after I built it until yesterday evening when I've switched off my computer (standard Windows shut down) and after about an hour I couldn't turn it on anymore. It gives a little TICK noise and that's it- no fans or system lights.

Turning PSU power switch on/off and then pressing computer power button- again TICK. If not switching off PSU, by pressing power button on case, no more TICK noise- it just does nothing. TICK noise comes just 1x time after switching off/on PSU. Pressed CMOS reset button on the motherboard- straight after I pressed it, got TICK noise and that's it, system is still not powering on. Removed most components from the board- again nothing more than a TICK. Then after a repeated power button pushes computer turned on. I then turned computer off and installed all parts back and the same TICK thing happened again. Fed up and started repeatedly pressing power button (5 or so times in a row) after what computer turned on- and worked fine, updated Windows 10, restarted couple of times and everything worked as usual. But, again, same thing happened this morning- after pressing power button few times PC turned on and now runs normally.

Any ideas of what could cause this issue? Motherboard? PSU?

My system spcs:

Regards,
Light

then try the psu paperclip test to see if the psu activates when computer starts up ?

You may have something screwy going on with your front I/O panel, it could be the contacts for the power button in the panel aren't working quite right, you may have a a loose cable, or it might be the connector on the motherboard side. I had something similar happen to my build, and I ended up having to find a weird solution, and just stick with it because it works.

My build was refusing to turn on after being unplugged from the wall, and plugged back in. I would get power to the MB, but I could not power the PC on from there. Every time I tried turning it on, I simply got the little clicks and no boot.

I initially thought it was the PSU, but I tried several different working power supplies, and could not get it to work. I eventually pinned the problem down to the motherboard, and I think it is just a weird little glitch it has. The solution I figured out was the first time I power it on after unplugging/plugging it back in, I had to hold down the PC power switch on the I/O panel, while turning the PSU switch on and off twice. It's a royal pain, but after that initial boot, it operates normally.

You may just have a quirky motherboard, or it could be one of the problems I mentioned concerning the I/O panel. I doubt it could be anything else since you can get it to boot after a couple of tries, and it runs normally after it successfully boots. The only other thing would be the PSU, but like I said, if you can get it to work after a few tries, it is probably not that.
