Fan at idle but no display

I recently picked up a power book 34, I went to turn it on, and it worked! Then next day I went to power it on and nothing, I saw it was a 45w adapter so I bought a genuine apple 65w adapter, went to turn it on, and the fan ran at idle but no display, tried at the textbook stuff, smc, pmu, PRAM resetts, but still no, any ideas?
