Hey and thanks for stopping by.
My computer was working perfectly for the past months and all the sudden, the PC wont turn on anymore. When I press the ON button, the fans try to move but then stop.
It's neither the PSU or the Motherboard because I've replaced these and the problem remains. I believe it might be the CPU but I don't want to spend more money on another part and find out thats not the issue either.

Help would be really appreciated!

So it does power up for a second? It could be something causing a power failure but am not sure what. May be a faulty CPU or even the case/case front panel leads. Unless you want to get it out of the case and try powering it up that way I'd take it for repair as it sounds like a pretty serious problem.

Have you done something as simple as checked all cables are attached properly? Take the build down to bare components (CPU, board, PSU and cooler) and go from there. Leave RAM, case fans, hard drives and GPU unattached. Even do it out of case if possible, as that could be causing a short etc.

No not likely the CPU as you should see some sign of life in the motherboard etc. I realise you said your replaced the board and PSU though. Do you definitely have both motherboard power supplies attached properly? They can take some force (but dont bend the board obviously).

Even with faulty CPU or RAM the board should still power up.

Yep, I've applies a lot of strength and nothing. When I placed everything back in, it went back to having the the psu, gpu, and case fans for a split second. Any cable in particular I should check?
