I have an AMD Duron 600Mhz computer with a gigabyte GA-7iXE4 motherboard, 64 MB SDram PC100 Dimm, CD Rom, Harddrive. My problem is my computer refuses to turn on sometimes. It seems to work, keyboard lights, CD Rom lights and then nothing. The reset button works but it does'nt set the keyboard lights again. I have the whole thing installed in a 250W case- could this be the problem?
