I built my PC about 2 years ago and recently upgraded a few weeks ago with a new case, New motherboard, a new WiFi adapter and soundcard. It was working fine until I went to put in some lights (LED strips) and a few seconds later my PC turned off. I thought I must of blew something so I bought a new 750w PSU, same as my old one, that was not the problem as it still won't turn on. I just literally 10 mins ago replaced my motherboard but it still will not turn on. I have taken everything out including testing the RAM in different slots. I have taken out the WiFi card and also the Soundcard and GPU, then all the other fans spin for half a second then stop (CPU fan and case fans, still no sound or LEDs/ lights) I have done the paperclip test with the PSU, but still no result. It's starting to really annoy me haha, just don't understand what the problem is. I think it would be a good addition to explain how the GPU fans all spin for about half a second and nothing turns on, no lights or anything. I first thought it was not getting enough power but now I'm thinking it is the GPU but still confused as to how that is possible.



Thanks to all in advance also PM me if you can and also post here for others to see if they are stuck with this problem as I am on a mobile device and would notice it sooner in my PMs :)

I would think your board is shorted to the case. Remove the board from the case and put it on the box it came in. Remove the video card and memory. Install just one dtick of memory and short the power pins out and see if you can boot into BIOS using the boards built in graphics if your processor has that if not then also reinstall the video card.
