I was getting the same errors recently, and I replaced my disk and
re-installed RHEL. I was pretty sure it was a disk problem since I could
hear _something_ in the case was not running smoothly. I don't get the same
problem (yet) but I still hear the same or similar noise. The problem I see
is that this on a dual boot system. So, if it was the CPU, why wouldn't
there be similar problems with booting XP? If it is a bad disk, the grub
partition is on the second disk with RHEL, so could a bad power supply only
damage the RHEL portion and leave the rest alone? Even after the machine
wouldn't boot into Linux, it would still boot to XP. In particular, I am
wondering now if the power unit may be too small to run the extra disk.
