I know this is a fairly common question, but I just want to try and give all details for specificity.
So recently, I came back to find my computer switched itself off. When I tried to turn it back on, it was unresponsive. However, if I turns the mains switch off then on, it would power up for a few seconds and then shut down again, but just once.
On closer inspection, I looked inside to find my PSU's fuse had shattered, and it had overheated. This was a cheap 500W one... to be expected after a few months.
I then replaced it with a 750W PSU I had in my drawer. It turned on then off again.
I replaced the fuse in the power chord to make sure. Still the same problem.
I tried looking for loose screws/hardware. Starting it up with minimal hardware. Putting the cmos battery out and in again.
Edit: My 750W PSU came from when my motherboard blew out. It did the 'infinite turn on and off' problem. Long story short, I forgot about changing it back.
Any tips?
