So, thank you all responding me.I have already tried all you adviced me, but something
new happened.I kept trying to boot my OS from cd and i made a bootable windows xp
cd.I booted from it but there were many option like ms-dos i'm not familiar with
so i turned it off and i copied my setup COMPAQ(my vendor's cd) into a bootable cd
and i tried to boot from it.Don't know how happened i logged in and no password was
prompted.So my OS was a disaster - so many things i didn't put there.I found out
that i was logged in as a guest and couldn't do nothing so i inserted the win xp
cd and tried reinstall windows.Windows told me that this xp can not be install ot
this machine so i tried repair it with setup COMPAQ but the computer was too slow
to do anything so i thought the password was no more and i reboot it trying to boot
from the cd and again there was this password and now don't know what to do.So this
is what happened pretty much.
