    Hey. Just installed new game on my pc, playing for an hour or so. Left on pause for Christmas dinner, came back afterwards and pc was off. Tried to start up and nothing. No lights or fans kicking in. Any clues? Decent enough machine thats a year old so is well able for it. Tried disconnecting hard and disc drives and usb from M.B. to power up to check the psu and still nothing. Not too sure what I am at though, only read on internet to try check psu.
    Cheers if anyone can help.

    Did you check the plug fuse , sounds simple but i had one go on me two weeks ago and was like oh **** no , then calmed down and changed the fuse and luckily it was that .

    i assume u plugged power out and back in and tried another cable (to rule out fuse) and assuming the mains power is ok it sounds like PSU alright

    Yea tried different lead. Think it is psu but don't want to fork out for a new one unless i am sure. Any easy way to do it with multimeter?

    your multimeter will have a continuity tester, make sure the fuse is out before testing, if the meter beeps the fuse is fine. If the fuse in PSU is gone make sure you get the exact replacement or you'll damage motherboard.

    Will that just check the fuse? I want to see if power is leaving the psu going to the PC. Or are you talking about a internal fuse inside the psu. I don't know much about them. Changed power lead so its not fuse in the plug.

    Cheers again for everyones help. :)

    theres an internal fuse inside the PSU, if thats blown no power will get to the motherboard. If you have no knowledge of electrics, its best left to the professionals, take it into PC World or similar.
