oh yes i forgot the graphic card fan is on anyway, but the long beep still on all the time, and there are no POST, because there is no visual display on my monitor. that's why i'm so confused by it. if the graphic card isn't fully seated then why the graphic card fan can be on. is it because my BIOS/CMOS had error on it. if it did how could i reset those, i already trying jumper thing, short circuited it, and take the battery of from it, but the POST and the BIOS/CMOS setup didn't come up in my monitor. thanks for the help.
