Hi all,

This is my first post!!!!

Ive got a problem with my PC. It was fine last night when I turned it off but today, when I tried to turn it on, nothing happened.

The Anti-burn light is lit on my motherboard and on my bluetooth dongle but the PC fails to do anything else.

Please help me!!!

Hello, and welcome

Have you checked all the connections are seated correctly?
Regards,

Alan.

What is the state of the PSU, is it new?
Can you get to the BIOS at all?
can you say in detail what happens when you press the power button?
Regards,

Alan.

I built the PC about 2 years ago (I think!).

When I press the power button nothing happens.

But while it is plugged in the board light is on.

Is the board screwed in correctly, it might not have been earthed or insulated correctly,
Do the fans spin at all?
Regards,

Alan.

The board is in properly.

The fans dont spin, nothing what so ever happens when I try to turn it on.

The PSU is working because the motherboard & bluetooth lights are on.

On the PSU, have the power settings been changed, it sounds that it is letting through power, just not enough of it,
it could be that the power button is damaged, it happened to a friend here, he pressed the on button nothing happened, took the front of the case off, found that the button didn't reach the connector.
Regards,

Alan.

No POST beeps? Like Nigglesnush85 said, it could be the switch, try jumping it. It's also possible it could still be the power supply. It could have a bad rail. What make is the psu and the mobo?

Follow the wires from the switch to the plug on the motherboard. Make a note of where the switch is attached to the mobo. and remove the plug. If you have a multimeter you could check for continuity across the plug while pressing the switch or, use a piece of small gauge insulated wire, stripped on both ends and short out the 2 terminals the plug was connected to, taking care not to touch anything else

Well, if it were me I'd just throw in another PSU, but I know people might not have them laying around. Here are a few links and diagrams to maybe help you sort things through

Sometimes PSU's will fail under load and operate correctly when not under load.

Try ripping everything out except for the PSU, mobo, processor (and fan/cooler) and then fire it up. Get any beeps? If not, then it's likely that one of them things is what's bad.

Have you checked the motherboard for buldged/bad capacitors? ( http://www.badcaps.net )

Do you have another computer handy that you can borrow parts from?

Just because the lights on, it don't mean that anyone's home. It only takes a smidgen of electricity along one path to light that light - all the rest of the paths could be broken and the light could still light up.

. . . I would of gone at it with a hammer by now!!

I'd have used a chainsaw! :thumbsup:
