Windows XP - boot issue?

hi guys,

bit stumped by this myself ... my sister's machine running XP fires up as normal, gets to the Windows loading screen, that dissapears, and then it just kills the power to the PC, and it restarts by itself, and then it just cycles throug this

It has no extra devices other than standard, i have removed all components to try and diagnose the problem, all seem ok including ram etc ... i have run a Windows XP repair, with fixboot and fixmbr and still the problem remains ... i managed to slave the disk to my main machine, and it reads the disk, files, and folders all perfectly, almost like theres no problem with it ... all BIOS settings are fine and back to default. I have tried the Winternals CD to see if there are any file system errors, all ok ...

can anyone think what might cause the machine to kill its power and restart just after the XP loading screen dissapears?

Thanks

if i check the event log in Winternals it says something about secur32.dll is corrupt and un-readable ... had a google around and not found much on it ... have tried a system restore back to a few months ago to no avail ...

confirmation boot?

wrong command? i was using chkdsk /r as per normal ...

chkdsk /p finds one or more errors, but when i run chkdsk /r it completes, but it doesnt say the usual "found and fixed one or more errors"

think i might slap an old disk in and try a new windows install
