Well what i am doing is trying to upgrade 1GB of PC-3200 (400) TO 2GB PC-3200 (400). What i have done first was make sure i was grounded before i open my case. I open my case. Then i take out the two 512mb of memory and replaced them with two 1Gb of memory. No big deal right??? Wrong! Now before i close the case i made sure that the video card is secured and the memory sticks are secured as well. The tower case is now secured. I turn on the tower then turn on the monitor, but the monitor is not responding. What is the little light by the power button is flashing. The monitor screen is completely black. There is NO warnings of any type or anything. Shut off the computer then i reopen the case swap the new ram back to the old ram and i am getting the same problem. The video card i have tested in my other system and it works with no problems. Now what is the answer to this riddle?
