You may want to try and gather what the OS is doing on startup, or whether there are any POST error codes. If possible, Windows XP/2000 machnes can now stop at the STOP error instead of rebooting if there's an error preventing Windows from starting up, rather than just rebooting on its own. Press F8 before the Windows logo appears and select "Disable restart on crash error" option. (or Something similar)
Hope this will help you determine the problem. --- In [email protected], Homer Loner <[EMAIL PROTECTED]> wrote: > N.
