Computer reboots w/acc the HD

[microsoft]

I have two computers that are rebooting as they access the harddrive on
bootup.
The first one is an emachine. Windows Xp had become corrupt. The system will
not let me resetup Windows, it stops on the Windows is now starting setup.
The harddrive works fine in another computer. I have exchanged the memory
that did not change any thing.

The second one would not boot past the bios. I put a new motherboard,
processor and memory in it. Now it does the same as the first computer.
These computers are each owned by different people in different homes.
The both have a blue screen that flashes so fast that I cannot get the
information from it.
Thanks Loretta
