So, I decided to purchase another stick of ram for my machine. My current stick of ram is a Corsair 512 MB pc3200 (ddr400) and I also purchased the exact same stick again (even the brand) to enhance my gaming performance. Here's the problem: Both sticks of RAM run perfectly fine - but only when it's just ONE stick in the system. When I put both sticks in, my computer refuses to even boot up. When I push power, everything powers up, but windows doesn't come up, nor does the starting bios screen, for that matter. What could possibly be my problem? Thanks for any help.
