Help can not boot

Hello,
Firstly thankyou to anyone and everyone who can help, and my apologies for being an unexpert in computers. i have best described my problem
My laptop has some issues, Windows only loads to the splash screen then jams.
I have tried to run scan disk, but there are so many problems, and one is too large to fix, it does not complete.
I can get to dos mode, but cannot load in safe or any other mode, as the computer jams.

ok, here is where i get to and the problems
when i choose
step by step config it loads
boottlog.xt
process startup device drivers (config.sys)
device c:winhimen.sys then no more response, the computer locks up.
OR
with a windows disk in drive
running win set up from e:
replace curent op system
scan disk - directory structure - invalid long filename entry and unable to fix
then jams when
searching c: for crosslinked files.
OR
choosing safe mode command prompt only - gets me to dos prompt with the mesage
divide overflow error.
then to the dos prompt.


Do i need a startup disk?
how do i start windows?
any help thanks!!!

Seems you are experiencing a hardware error (Faulty Motherboard, RAM, HDD, etc.) since you are getting errors even when just booting to a clean DOS prompt.

Have the machine been booting properly before ? And if so what changes have happened before it started not to boot ?

 

thanks for the reply, the problems ive had before are a loose power cord, so power is often dropped whilst using the computer with no warning.
Other than that, the computer normally then runs scandisk and starts.
other than frequently cutting out, no hardware / software change have been made.
thanks for your help
