Cause of repeated rebooting?: Power failure!!

Hi fellow mates

Circumstances
1 AMD stand alone PC with XPWin SP2 starts perfectly for years.
2 Then recently during copying of files, power failure occurred.
3 On restarting, as soon as XPWin startup bar starts, a momentary DOS (blue) screen message appeared (can't read contents, probably a serious of numbers requiring rebooting) occurred and it reboots repeatedly on the same loop.

What i normally do to resolve such event
1 Boot in safe mode, Shut down & boot in normal mode
2 Schedule a scandisk and do it.
3 Restore the registry backup

With the combination of the above 3 steps the PC can start & run in normal mode. However the sad news: xpWin starts on the same sad loop after having shut down from a normal XPWin session.

I have read this forum's issues relating to AMD & its registry entry, Autorestart on the My Computer Advanced settings, cooling/powersupply stability, etc but I have a feeling it is not due to any of these.

The funny thing is:
Using Norton Ghost I clone this 1st harddisk to 2nd & the 2nd DO NOT manifest any of this symptom. That got me thinking of searching for the real causes in this forum.

Hope some great guy can HELP the

 

A failing hard disk perhaps.

Download & run the manufacturers utility for your hard disk.

 

Thanks mates

Questions
1 Don't a full scan by ChkDsk identify any corrupt files as against "system checker "?
2 If there is a harddisk error, how is it i have no problem to ghost.clone in Dos mode to 2nd hard disk that don't have the repeated rebooting.

More puzzling!!: The 1st harddisk after resting a day don't manifest this repeated rebooting anymore. Does this confirm that the 1st harddisk has some intermittent hard disk corruption.?? If so is system checker the best way to check?

 

No Chkdsk/Scandisk confirms that it can read the file, sfc does have the means to validate the file.

Reading and writing are two different things, perhaps ghost is a little more tolerant than windows startup?

My opinion, forget resting the first harddisk, it's failing. Back up the data and run full diagnostics on it. Think of it as a spouse, I won't do it again honey I promise Yeah right.

 

W.F..: Advice & Pun fully noted. Thanks for the effort. Period.

 

Period: Cause - not fully shutdown

Hi everybody

My final conclusion of this phenomena are as follows:

1 It is very likely that it is not a hard disk failure problem as after the so called "resting" of the hard disk no such problem occurred at all for 4 weeks over.

2 Moreover I did not do a repair of the xpWin.

Period:
Yesterday after cleaning up of the registry plus repeated rebooting, the same problem of failing to reboot occurred.
The solution was quite simple. Just switch off the system totally for a minute, then reboot, the problem stopped. I believe that there is some data in the RAM or some resident info that was not completely cleared at rebooting.

Hope this will help others who are facing the same problem. Cheers.
