PC is totally dead.

moonpenny

PC was perfectly ok last night but switched on tonight and its dead.
There is no noise or anything from tower and no light when switched on. The orange light comes on the monitor button and then it says it is going to sleep but nothing else on monitor.
WiFi and printer comes on as normal though WiFi modem flashes a bit before it settles.
Nothing loose on plugs and connections but I have no fuses to test if maybe the fuse has gone on main plug.
What else could I do if not the fuse?

Assuming the mains socket works there will be a fuse in the plug and a fuse in the PSU.

So the monitor is plugged into a separate plug socket - and the light is coming on the monitor.
But the tower is plugged into a separate plug socket and no light comes on the tower at all?

Have you tried swapping the plugs around - ie plugging the monitor into a different socket? It could be your plug socket not working. Although that's never happened to me before, so it must be rare.

Come to think of it, I haven't changed a fuse in a plug for at least 20 years now. Maybe some things are being made to last these days!?

Everything connected to my pc in plugged into one of those long plug strips and the light on that comes on.
I have swapped plugs around into different sockets on this and its no different.
When I try switching it on, I press the tower button that should light up blue but nothing and the I press the monitor button that should light up blue but it lights up Orange with the message it is going to sleep. It light orange normally when it is ready to be switched off.

Dead PSU? (or blown fuse if it has one). Try this - with tower plugged in, turn OFF power at the mains socket; then press and hold power button and count to 20; switch mains back on and try tower switch again.

Does your PC have a small light on the back of it and if so, is it lit? If so, it is not your plug and more likely to be the PSU. If not, it could be any of the things referred to above.

How old is the PC?

It could be a failed Power Supply. I had one fail on me last year after about 16 years. It was a good make so lasted a long time. Cheaper PSU's won't last anywhere near that amount of time.

You can buy cheap PSU testers on Amazon and eBay which you plug in to the PSU connector after removing from the motherboard to test the PSU. You might need someone who is good at technical things to do it if you are not so inclined. There are other more technical methods to test them by shorting pins but that will not appeal to many.

Fuses very rarely go in plugs these days, if an item develops an electrical fault the RCD switch will usually trip first.

Of course if the rest of the devices on the electrical circuit are working and you haven't had to reset the RCD, that points to an issue with the computer, and it's going to be a dead power supply.

Most machines use standard power supplies and you can get these from Amazon, eBuyer, Aria, etc. If you post your brand and model number somebody can check what it takes.

You've piqued my interest, what would this achieve?

If your monitor uses the same lead as the PC (the 3 pin kettle lead) try swapping them around. That will rule out the power lead and fuse.

Unfortunately if no success that would mean it's the PC itself, the PSU would be the most likely culprit, the leads internally usually use clips so it's difficult for them to loosen but it won't cost anything to check. Anything beyond that is going to depend on your ability to dismantle your PC to possibly replace parts but doing it in a random way can be expensive. See if there's any local PC repair shops (if they still exist).

Have you (or one of those naughty overnight gremlins) accidentally (or deliberately) pulled the kettle lead out of the PSU. Or and I don't know why/how this could happen, is there a switch on the PSU that has been inadvertently switched off?
