Simple enough right? I got two new PNY 512mb DIMM ram to put in my Dell Dimension 2300 series with a 1.8ghz, According to the memory companies and dell this should work fine. On boot up it reconizes the memmory and under hardwhere check the memmory is okay. (i also had a computer shop check it out) Long story short when windows loads it crashes, with various errors, never quite the same ones. Using only one of the memmory sticks will allow boot up but all the programs will crash and give and unespected fault error. Anyone got an Idea?
