Computer wont start up

yeah they are on mate, the motherboard is not connected directly to the case

Do none of the fans spin at all when pushing the power button?

You may have a faulty power lead on your case. Do you have another case to try?

If not then there is an alternative by shorting the two pins on the motherboard to see but not sure how you do it.

Can anyone help with this?

i did actually think myself it could be the case, i put all the component into another case and it didnt work either. i dont know whether the cas i tried still works cos its really old but it still didnt start up. Nothing happens at all when i turn on the power button

If the motherboard appears to have power (do you have an LED showing) and its not starting with the power button... do you have the power lead pluged into the correct jumpers on the motherboard?

To rule out the power button (although it isn't likely as you've tried it in a different case already) Just locate the two pins which are for the power switch cable, then short them with a screwdriver...ie place the screwdriver BETWEEN the two pins. Try not to touch any other pins while doing this, as you could short the board out as well, you'll know if you do this cause you sometimes get sparkles :rolleyes:

To me it sounds like a duff mobo or cpu, if you can try a different cpu in your board, it would help out a lot...And if you can try your cpu in a "definetly working" motherboard, it would sort out that issue as well.

Try and do all of this out of the case on top of an antistaic bag or something, just to rule out the case shorting anything, but going by what you have been saying it seems unlikely anyway.

The power cable connecting to the mobo does not fit all the pins, it is like 2 pins smaller i think. but its the same on my bros pc and he hasnt got any problems

In answer to this, I believe you mean the 20-pin power cable? the one on your board is more than likely 24-pin, but it will still work with just the 20-pin cable connected.

Have you tried re-seating the cpu as well? Could try booting up with leaving the cpu-cooler "un-clipped" as well, so it's just resting on the cpu rather tahn being fully locked on and possibly bending the board a little.

Obviously don't run it like this permanently
