My pc's power supply had lost 2 of its capacitors (after a Loud double poping sound. The original psu was from Deer computerc co. and it had 250W Anyway i had just bought a new psu that has 300w instead of the 250 and it comes with 3 new connections that the deer one didn't have the p4 ata and another white one i forgot the name but when i connected all the wires to their proper place for some reason when i power up the pc the fans move for only a second and then thats it nothin it won't power up at all!! even when i just leave the main wire to the mother board.did i miss something here? (the pc is atx and i purchased it in may of 2000) PCBUILD maintains hundreds of useful files for download visit our download web page at: http://freepctech.com/downloads.shtml
