    Ok, feeling confident I thought I'd upgrade my MoBo and Graphics card.

    Managed to connect everything up as per the manual. Try to repower and nothing, zip, nada, zilch ...

    So, replace the old MoBo and get the same result, zip, nada!

    I'm putting guesses at the PSU ... Or have I missed something?

    Does the fan for the PSU spin up when you press the power button on the machine?
    Check all the connections again.... and let us know. As you say you were upgrading it is unlikely you have 2 dead mobo's...

    I get nothing, not even the friendly hum/ whir of the PSU fan ...

    Checked the connections and they are seated properly.

    Check the jumper for the power switch on the mobo Dude - I've run into this one before. :rolleyes:

    I take it it is an ATX power connector coming from the power supply?

    If the old mobo was working fine before there should not be any problems with the PSU!
    How about the connector lead that goes from the power on switch to the motherboard.... is this connected?

    I'm not completely dumb. The power from the mains is still working - the light from my monitor confirms this.

    I've rechecked the connections and everything is firmly in place and in the right way.

    All leads from the PSU are in the right place, re-checked the MoBo manual.

    Re-placed the power switch jumper, again re-checked the MoBo manual.

    Looks like a trip to local Computer store for a new PSU is in order. Unless anyone has any other bright idea's!

    I am not saying you are dumb. I was merely pointing out that just because one thing was working it doesn't mean the other is.

    Have you got a multimeter? If yes, then check for an output (DC) on the yellow and black wires. You should have 5 volts. On the red and black you should have 12 volts.

    If all was OK before you swopped the mobo over then it sounds like a wiring issue to me...

    Let us know how you get on.

    It does sound PSU related if you are absolutely sure the wiring is correct. Was it an old PSU? Perhaps your new power hungry components have pushed it over the edge!

    At least you can now get a brand new PSU, not as glamorous as getting a new graphics card but sometimes installing a PSU that makes little noise can be a worthwhile upgrade. 8)

    Sorry ... Didn't mean it to sound like I was unimpressed, far from it. (Tone of voice really doesn't work in these forums)

    I've done all the obvious stuff like checking wiring/ power supply from mains/ connection seating

    I'll re-check everything again tomorrow, including re-trying the old MoBo and double check everything, try a new PSU and let you guys know the outcome!

    Anyway, thanks for the pointers guys, much appreciated! Beers on me :morebeer

    Hey mate, I'll go with Sparky here, your new machine maybe stretching the old PSU just a tad hard and a new one is in order. What power rating is the old boards and what is it trying to power?

    Tone of voice doesn't always translate well at times, but that sounds good to me. Mine's a Guinness ... :wink:

    Often a time spent away from the problem makes it easier to come back to afresh - good luck with this.

    Knight,

    No problem matey. Just imagine my text in Boyce's sarcastic tone!

    If you are sure all the connections are right then it could well be the PSU gone toes up.
    Don't forget to go here to work out what PSU you need. Tagan or Zalman are good'uns.... Try www.overclockers.co.uk

    Don't forget to let us know the outcome :thumbleft

    My monies on the PSU too.

    The PSU is usually the most likely thing to cause a dead computer. On this occasion it gave up the ghost when you upgraded components and as others have said, the new motherboard and graphics card may consume more current than the old ones. Chances are that the PSU was on it's way out and the new components were the last straw.

    Let us know!

    Just to let you guys know of the fun I'm having. Ordered a new PSU from Novatech which promptly arrived yesterday. Just opened the box to install it and they sent me a 24 pin PSU and not a 20 Pin like I ordered.

    The good news is that they're based just down the road from where I work so I can get it changed easily on Monday! Will let you know Monday or Tuesday how I get on ...

    We have power ... :D

    PC has power ... Now to get the MoBo working! Keeps resetting, so I'm guessing I have to reinsert the old MoBo and install the drivers/ disable the old driver.

    Who'd have thought upgrading would be so much hassle!
