Hey guys, well I have an old 5240, it worked fine then one day the net stopped working on it, so i figured meh, lets mod it! All I did was take the black fan outta the psu and try to put a green led fan in it. Wel l did so, and it didn't work so I was F#|< it, well, now I'm looking to get it runnin again but the psu doesn't work, its an AT style but it has 3 plugs, all I've seen of them they are like 80 bucks fora 110watt psu! Any one have any clue asto whats wrong or where I can find one for cheap? Its a Mitac MPU-110REFP by the way. Thanks for any help guys.
