  1. Well i know i did not have any reply,i hope this is useful to any one that loves to get their hands dirty inside a pc,
    some hard work paid off,i went back to my pc and took out all my cables,i have a modular power supply,the wires that are attach to the psu are the ones i was using,and they were wrong,they really do not supply so much power to substain the hardrives and the dvd roms,in this case i was not able to detect my hardware in the bios,and not able to install the ops,
    now i have all separated in the modular and everything is detected,
    thanks all.
