It will for about 6-7 times. From what I read it doesn't mean CPU is bad, just the the KB memory gets full and it can't light up anymore. I was wondering if anyone has a doc or something that can walk you through troubleshooting a motherboard. Something that tells you what maybe the multimeter readings should be for different chips. Also how to test the power supply. I am kind of thinking that might be a problem possibly since this is the second MB and second 3640 card in it. Any ideas?
Something else to check...
Under the cpu board is a set of jumpers for int/ext.
If they are set incorrectly for your cpu, it will hang the system.
BTW, If memory serves, for the 3640 should be set to ext.
