In this video I show the steps I take when trying to diagnose a desktop computer that power cycles after pressing the power button. Testing each component one by one to try to narrow down the problem. When doing fault finding it's important to test all parts of the computer to find the failing device.

You didnt test the power button to see if it was stuck on ON.

So did the customer end up buying a new computer, go for a motherboard replacement or what?

The reason Re: the mobo, is bc it is a pos. Good vid though Tim and thank you very much for giving us a vid to watch other than one about the sorry freaking state of GPUs.

I have to turn my gaming PC on twice to get it started. I press the power button and it lights up, but no picture. I have to long hold the power again to turn it off, then push power again and it boots up perfectly. All front power connections are in the right place, but no matter what I do, it happens every time! Any ideas? Anyone? Great video btw👍
