i was having a problem with my computer, i thought it was the motherboard problem or the processor thus i replaced them.

After that ,with the new hardwares, the monitor no signal, mouse no power keyboard no respond, but the cpu fan, graphic card fan are working.

plus the lights on the casing that are suppose to flash at the start is dead. the casing light the the 'on' button is dead also.....

i tried popping up rams graphic card checked all connections, there seems to be nothing wrong.

so i thought maybe it is the power supply 's probem. after posting at the
PSU section i was suggested to change my PSU, and i did, but it doesnt seem to work...

so im thinking if it is the motherboard and cpu problem ?
i really need help on this...

mother board:G31M3-f
ram:2x 512mb kinston
graphic card: ATI1600pro 256

new power suply: cooler master, 460w

I think you are still underpowered. When you installed motherboard
did you use the brass standoffs? Are you sure there all in the right
place? One standoff in the wrong place can cause a short, which
can kill the board. You should try and run the mobo outside of the
case. This will eliminate the possiblity of grounding. Double check
your connections.
Im not sure with that psu if it will boot anyway. You need at least
26amps on the 12volt rail/rails to operate a pci-e video card. Then
if you factor in that the psu is only %70 effieceint, do the math.
It may be ok, but I like to have some overhead...
