I have a Dell Dimension 4400. My problems started with a hard disk failure (I think?). So, a new disk drive was installed, 512 Meg memory, and reinstallation of XP Home. Ever since these events, I get the Boot Failure message on a Cold boot. Most of the time when I do a cold boot, XP will come up with no probllems. If I then shut down and do another cold boot, I get the Boot Failure message. I think it is a heat related problem, because if I let the computer sit for about an hour or longer, it will boot up again OK. I replaced the Fan so that was not the problem. As a note, if I do a Restart on XP, it will boot OK every time. The problem is only on a Cold Boot after the computer has been on for a while. Any suggestions would be appreciated.
Thanks, Tom
