PC Dead as a Doornail!

[motionman]

Yesterday evening, after a normal day's use I shut down my desktop and turned in. This morning, I pressed the power switch as usual but there were no signs of life. I have checked the power cable, plug, fuse, and power supply from the mains socket (via a surge protector). All were in working order. The monitor, which uses the same surge protector, displayed its usual power-on light.

Leading up to this, something spinning such as a fan or another component has been making more noise than usual. I don't know if this is connected to the boot-up failure or not.

I'm guessing that the problem lies with the PC's internal power supply? Before I follow this route, are there other things that I should check out first?

I'm running Windows 10 Home 64bit.

You can try the paperclip test on the PSU. This will tell you if the PSU is totally dead or not, although it won’t tell you if the PSU is able to deliver it‘s full rated power.

Hello David and thanks for your reply.

Confession time first! I went back to the srart line for a second time and checked the AC power supply and re-seating the plug into the socket on the back of the case had a miraculous effect. So my lesson learnt was to check slowely and meticulously and don't ignore the basics.

Thanks for your link. I had a look. I didn't recognise the 24 pin connector. Were can I find this?

This is the main standard connector on any ATX motherboard. Follow the main power wires from the PSU to the motherboard.

Thanks David. The paper clip test is a handy one to know.

Love the honesty, I would have lied.
