Hey I am building a new Athlon XP system and am having a bit of trouble.... When I assembled everything and powered up, NO SIGNAL went to the monitor! I switched vid cards... no luck. I removed every pci card, just leaving the AGP vid card... no luck. I tested the Vid card on another system... nothing wrong with it. I removed the heat sink and inspected the processor... no cracks or chips, and it otherwise looks perfect. That leaves the RAM chip and the EPOX motherboard. DDR RAM chips hardly ever are defective, so do you think the motherboard is???? Thanks!!
