computer will not boot

speedy6 · 10-06-2008, 04:13 PM

Hi, I'm having the exact same problem... except prior to attempting power up, I had to change like 20 capacitors on the mother board (ax45-v/961 chipset)... the only difference during power up is that it makes a very high pitch sound(like a capacitor charging in a camera) all capaciors were replaced with same value(except temperature rating 105c replaced by 85c) now I'm not certified to do such operations but it doesn't mean I don't know what I'm doing... I'm going to attempt running it "out of the box" as you mentioned

start it by touching the 2 pins on the m/b that the case switch connects to,with a paperclip or small screwdriver
and see if you get post

meanwhile here are the remainder of the specs Aopen ax45-v with a P4 1.7ghz/256/400/1.75v and an ATI radeon9250 video card powered by a 420w... is the temp rating the cause of the high pitch sound...?

jack of all trades in need of master's opinion

ok, so I tried it out of it's case and the power suply was the high pitch sound issue, it tested good on an other board... my ax45-v won't boot up at all if the 4 pin power is connected to the board, and it boots without it but it doesn't display video or read any drives, but the fan starts up... I'm just troubleshooting from my best judgement and common sense, but I'm at a point where I'm a little lost... I guess my next course of action is trying diferent cpu or different video card, wich I only have th one agp and the other video cards are pci and quite old... is there a better direction I should be pointed to??
