    Hi people, got a slight problem, a friends computer would not start up,switched off at back of PSU then unpluged the mains cable, then after putting the cable back in and switching on the PSU went BANG!!!!!!!!!!!!big sparks and computer was dead

    susspecting the PSU had gone a bought a replacement 300w one, now then plug in all cables to test and powered up the computer and all was well, puter started up okay, played around with it for half hour then switched off to refit PSU propally and replace panels,,,,,,,,after doing this the computer wouldnt start up again, im stumped ive checked all cable ,im positive I didnt damage anything putting the PSU back in!!!!!!!

    any ideas?, power supply is defo working because I gave it to a friend to borrow and it starts his computer up fine

    have I damaged the mobo, is there any test i can do?

    any help would be great cheers people

    Does the system seem completely dead? No fans or anything? Is the LED on the MB lit?

    Just double check obvious things if you haven't done so like the power cord, power strip and outlet.

    I dont think its your cpu or processor as they were just working before you installed your psu. I would suspect the psu u just got....have you tried another powere supply?

    Actually I am thinking just the opposite. When a power supply blows like that it frequently takes the motherboard out with it

    But why would the pc work with the new PSU? and then stop... Trying a diff psu is the first thing i would try...that would route you to the mobo if it didnt effect nething

    cheers fella, tried a different psu but still dead, so tried my processer in another mobo with the psu I bought and it started up lovely, so I think we can saftly say the mobo has gone, Its a socket A so im guessing £20 for a new one

    Thanks again for your help
