I just assembled my computer today, and it POST intitially and i hit F1 to continue, i install windows XP from a CD and then it goes to reboot and the monitor light turns yellow as if there is no acitivity and nothing happens, the only way i can get the computer to POSt again is to reset the cmos, then i can hit F1 and it goes into windows, if i try to change the bios i will go to save and exit, but it resets the computer and i am left again to reset the cmos or never POST again. I have an athlon 3000+ with 512mb kingmax 4000 Ram, ati Xtasy 9200 se video card, and a maxtor 60 GB hard drive. Everything works fine until i go to reboot my computer, and it just wont, unless the cmos is reset, any help would be appreciated.
