This is really just a quick question. My computer was failing to pass POST a while ago, so first I checked my graphics card but it was fine. I have two 512meg sticks of RAM, I removed one of them and now it appears to be working fine. I have had some trouble in the past with one of my sticks of RAM, sometimes my computer would only say it has 512meg sometimes it would say it has the full 1024. So my question is if it is possible that one of my RAM cards is dead and that is why it was failing post? If it was dead would that cause it to fail, or would it still turn on fine but only display 512meg of RAM?
