I have an old PC. It had two 1gb sticks of crucial pc2 6400. I bought two, 2gb sticks of pc2 6400(not crucial) and replaced the 1gb sticks and now no post. Ddr2 mobos should all have a minimum Max of 4 gigs right? Or do some have a 2gb Max?
well then check ur bios version and see if u have an update, then update it. First read carefully how to install bios on ur mobo. https://www.youtube.com/watch?v=U8IBbrYq61E - this is one way but u use ur bios file not that one in video xD
