My Win XP machine gave me the blue screen of death yesterday. Then when I rebooted, during POST, I got a messaqe that no hard drive was present. I tried rebooting once again and now get absolutely nothing. Not even a beep. If I remove the memory sticks from the machine, I get beep codes that tell me the memory is missing. If I put either or both sticks back in, nothing happens when I turn it on. Is there something that I’m missing in troubleshooting? Thanks for your help. Steve
