Hey everyone, thanks for checking my thread and offering help!

My system is as follows:

Graphics Card: nVidia GTX 750ti
Motherboard: MSI Z97 Gaming 3 Intel LGA1150 Z97 ATX
PSU: Corsair CP-9020049-UK VS Series ATX/EPS 80 PLUS Power Supply Unit, 450 W
Ram: Corsair CMZ4GX3M1A1600C9B Vengeance 4 GB (1 x 4 GB) DDR3 1600 Mhz C9 XMP Performance Memory Kit - Blue x 2
HDD: Kingston SSD A400 Solid State Drive 2.5 inch SATA 3 - 120 GB

I was using it to play a game on my PC which is easily playable usually and it started to lag massively. I thought nothing of it, uninstalled and reinstalled the game and it's fine. Today, I was doing usual things (netflix/gaming) and system crashed. Thought overheat, it crashed 3 times after later on. I took it apart, and noticed no matter what I take out/replace, every time I turn it on it does one of these things:

-All fans go. No LEDs on case itself turn on... Nor is there any display on monitor.
-Fans start, then switch off. Then on, off, etc...
-Fans start, LEDs go on, and display comes on as normal. <--- Very rare.

Reseating Ram, trying it without my GPU in, all of it doesn't work. I even tried a different power plug, from a different socket and nothing. It's completely random. Power is going to everything, the motherboard shows its recieving it (an LED is on it) and the GPU the same... Any ideas? Thanks in advance guys/girls!
 
Solution
disconnect all PSU cables from the motherboard and then reconnect them

it's acting as if the CPU power cable has an issue or isn't making a good connection

it might be signs of a PSU issue, but could be something else

after reconnecting the PSU cables, try a CMOS reset

seen to me like a cpu problems , I had burned one of my cpu in the past but it was a cheap pc that i did not care about and it did what your pc does , it turn on and off none stop and nothing on the screen , but you said that it sometime start , so i would check for the cpu cooler and make sure that it does its job and touch the cpu there might be a gape between cooler and cpu , or might be your psu but you said it close because overheat so I more think its cpu , is there any dust on cooler ? if so remove it
