Windows XP reboots during startup (endlessly)
Posted by dug on October 24th, 2005


Hi all,

Im having issues with my winxp. On boot, it goes to the screen of how
do you want to start windows (start normally, last good.., etc etc) all
selections lead to the same results. You select an option and the
machine reboots itself. I even tried the Repair mode off the CD, but
when you have to select the Windows directory you want to log onto,
again reboot. Nothing seems to work. In Debug mode it seems to get to
the Mup.sys file or after it and then reboots.

The hardware is all fine, just seems like xp got corrupted.

Nothing I have done up to now helps. I would appreciate any assistance
in this regard.

Many thanks

Probably a hardware problem;

If you added new hardware the OS would reboot several times to get the
right virtual device drivers loaded.

What is your power supply rating in watts, e.g., 240 watts?

If the OS just keeps on rebooting, you should look for a power problem
with your motherboard.
-Open your case and see if your capacitors are swelling or leaking.
These capacitors control power distibution on the board and if they
go bad you should replace the board (easier than repair)
-You can try replacing the CMOS battery, but your symptoms indicate
capacitance issues.

TIA,
