When your motherboard was broken down be sure to test parts before thinking it was flat dead and acquiring new ones. Be, by all means, to do a visual check up of the motherboard to make sure all IDE cables are connected correctly, the fans are rotating, and that the CMOS battery is in it’s own place. Moreover make sure for any busted or leaking capacitors; those can instantly cause motherboard to be considered as dead.
Be definite that all of the jumpers are in place as well, in case you didn’t know about jumper setting please check the mainboard’s manual for further information, and the manufacturer’s website to find the manual for jumper setting
