Power Loss

Hi all.
Got a snag with my old computer which somebody out there might know how to fix.
Just upgraded to an ATHLON 2.2 chip, so swapped my hard drive, cd writer & DVD rom drive from old case into new one.
Put a 30gb drive, an older cd writer and CD rom drive into the old Athlon 800Mhz computer with 512mb Ram. Switched on and nothing happened - no noises, no power pack fan running - completely dead. Assumed tha it might be the cable connections, power lead, electrical socket, ram placed correctly on motherboard - checked it all with nothing apparant. Even bought new power pack thinking that it must have died by shear co-incidence when I swapped the bits around - this has had no affect, so it's not the power pack. Unplugging and reconnecting the ATX power connector from the board gives a quick burst of life to the CPU fan then nothing again.
Cleared the BIOS settings with the motherboard jumper - still nothing.
Next step is try a new motherboard on the assumption that I must have killed the old one - but thought I'd pick your brains first - don't really want to commit to another £47 to find it's not the cause.
Can anyone help? Might this be something you've had? Any ideas?

  1. change your power supply with at least 400 watts
  2. Hiya,

    Unplug everything from the board, leave a mobo/ram/cpu and gcard. See if it boots, if it does, plug each item in one by one and find the offending item.
