I was given a bare bones mother board the other day and recognizing the CPU as a Intel Duo Core 4500 I decided to try and get it to boot up, I managed to get the CPU fan ruining and AGp card fan running but no post or video signal whats so ever, the key board and usb slots also seem dead. I checked all the fuses and caps on the board and all seem OK. some of the LDO's in the CPU area do not have 12 volt power going in or out!
The attached photos are not very clear due to the weather at present, the only service manual I've found for this board was on a Chinese web site, acer only give the owner manual which is as good as tits on a bull!
Anyhow the in the service manual they have the board hooked up to a 20 pin PSU although the board has a 24 pin slot, at present I've got it connected on 20pin but I do have a 24 pin PSU, if I connect the 4 pin 12 volt power near the CPU the board give the alarm, I think it was 4-5 long beeps and shuts down. Is it possible that he CPU is burnt or the onboard chip???
