I tried adding a stick of ram and after doing so computer won't boot. I press the power button, fan starts spinning, blue light on power button glows, system beeps, then blue light atarts flashing and nothing after that. I tried pulling the new ram out leaving old in, pulling old ram out leaving new ram in. Same story each time. I don't remember grouning myself prior to installing new ram, but have been doing this for 10+ years and can't believe I wouldn't. Any chance I haven't blown the mb and if I haven't, any idea how to get this thing to boot up?
