Cimputer won't POST

[CrixxzeH]

Hello,

As the title states my computer won't boot.

The computer was working fine yesterday my brother was on it watching the football. Anyway I've gone to turn the pc on today and got no POST.

The computer turns on, no signal on the monitor keeps switching between hdmi /analogue. After about 10 seconds the computer will just turn off and reset itself.
The led on the cpu coolers goes yellow /orange before this if this helps.

This is all just about confusing since my brother claims he used the computer to go on the Internet and watch football and now the day after the pc won't POST.

Please can you help with this and tell me what could have happened for the computer to not Post, thankyou.

do you have a on board GPU you could try or a spare GPU you could put in?

does the PC make any beeping noises when booting up?

On board GPU is available.

Do not have a gpu spare to test.

Computer won't boot to bios in order to enable on board GPU unless yit does it automatically when the gpu is disconnected.

As bad as this sounds could anybody spec me an replacement psu and motherboard that is reasonably cheap and will get the job done, don't want to spend too much with chriatmas coming.

Thanks.

Firstly, thankyou to all of the people who took their time to spec me components it's appreciated. I've sent the system off to be fully tested it's looking like a mobo/psu fault atm have not tried with one stick.

Honestly where do I begin?

Computer has been fixed. Hoooorah.

All components taken out cleaned and refitted and, turns out this was just a faulty kettle lead.

Thanks for all the feedback it'a appreciated.

Thanks, crixxzeh.

Faulty kettle lead doesn't sound right.

That's what the person said who rectified the fault with my Pc. Haven't seen the person face to face but will add more detail when I know myself.

So after the next day of the system being given back. The same problem is still occuring.

Even with the new kettle lead.

Im seriously thinking this could be a faulty psu, why?

Because like one person said on this post already, when the kettle lead is taken out and left for a while and then put back in, the system will actualy boot up and start as if nothing has happened (play games etc).

This is really, really puzzling me.
