hi everyone!
i am new to all this
but my computer died and i decided to have a crack at fixing it myself
i knew it was the mother board so i replaced it with one i brought off ebay. i also replaced the power supply. by the way its pentium 1.6 and uses socket 478b.
so my problem is wen i connect the power supply to the old mother board the fans spin in the power supply....no worries right, it shows signs of life. but wen i connect it to my new mobo and the power supply doesnt spin or anything. im completely confused about this. the mother board and the power supply are not compatable together?
anyways if anyone can help id be very greatful!

THANKS HEAPS

It's possible that they aren't compatible, i.e. the PSU isn't designed to support the motherboard. However, that shouldn't prevent the PSU from operating; it should still spin up. Normally the PSU would be working but you couldn't get the system to boot up.

There might be something wrong w/ the mobo itself, like the power connectors are broken. But again, it shouldn't prevent the PSU fans from running.

Basically I'm at a loss to explain why it works w/ one board but not the other. Does it work when it's not connected to a board at all?
