I am having a serious problem with an XP desktop PC .
Scenario
PC goes of without shutting down because of loss in power from the UPS,on charging the UPS and booting it shows "wrong CMOS settings".I set the CMOS settings, /date,/time/Boot order and all that stuff.System boots only to reach the Windows loading page it shows a blue screen and restarts! I am really confused.It doesn't even enter safe mode,the same blue screen takes over and it restarts.

Your system is infected virus after you download something yesterday you did not know that file contained virus inside to spread your hard disk drive replicate destroyed system file that make WACK restart itself over and over.

Have you install anti-virus on your system to protect from harm viruses?

Have you responsible to update your anti-virus periodically? Scan them on your system too?

Do you know that there is over one millions viruses without anti-virus protection installed on your system?

Recommend you get Hajack This software and any one of those anti-virus software (Avant, AVG, Nod32, McAfee, Norton, etc.) download to delete your infected system. Then clean up your system using Windows XP/Vista Disk Cleanup.

Google it! Also there are many NL threads answered your problem using NL google.

call me on 08055402226 let me give u tips on how to format ur system

@Double N

There could be a lot of things responsible for that. To narrow it down, can you note and post the error message you get at the Blue Screen Of Death here on this forum? With that, our suggestions would be more guided.

The systems boots up and shows Wrong CMOS settings, and says Press F1 to enter setup and F2 to load default settings.
I then pressed F1 and entered the setup to set the date time and other boot parameters.After reboot it shows the message"Windows did not shut down properly and shows the options of safe mode,safe mode with command prompt and load last known good configuration.After selecting load last known good configuration it boots shows the XP boot page and then the blue screen pops up and it restarts.On booting again the CMOS settings are still wrong!

use the win xp bootable CD to boot your system. It will get to the option where it will ask you to press ESC to install fresh XP or R to Recovery ,
Just press R and at the "look-like DOS prompt ",
type chkdsk /r or chkdsk /f
U will see some processing on your Hdisk.
It shld work and else follow uspry1 instructions.

I will do that as soon as i get home.Thanks.

I also have the same problem the only diffrence is dat it does not even give me the opportunity to format the system pls what do i do

Shola's path will get you to manually force the restart. After you restart there is still a path you need to follow to remedy the problem so it doent happen again. Here is that path,

START>
Control panel>
Power Options (if you are in classic view)> Performance and Maintenance (if you are in category view)>
Power Options>
Power Options Properties

Here you can manage and configure settings for optimum power management.

It woud seem your cmos battery has problems, this would explain why your settings reset every time you reboot. The reset of settings could also have undone windows. Try setting everything to default settings (should be an option for this somewhere in your bios) AFTER replacing your cmos battery (on the motherboard, new one should be no more than 250).

@Double N
As has been mentioned you should replace your CMOS battery and post the error code.
Some options available are
1. Repair the installation using the Windows XP Boot CD or
2. Download ultimate boot cd from http://www.ultimatebootcd.com/ burn it to cd or follow the instructions to install on a flash then use it to repair the boot sector of the disk. The stress is only necessary if you have important files on it. Or
3. Using the Windows Boot CD, delete the previously available partitions and do a fresh installation. (This will wipe all the data on the hard disk)

Hey Guys thanks for all the help.The Desktop is working well now. I changed the CMOS battery and re-configured the setup.Then i used the Windows XP installation CD to get into the recovery console and ran a chkdsk /f to fix any errors and voi'la! It booted up fine!

Nice to know you've resolved the issue now!

Cheers

even though the issue is resolved here is what probably happened:

BSoD is also known as Stop Error Code 0x0000000A and you probably see something like the attached image


What these parameters are telling you is this:-
0x0227001d – is an address that was referenced incorrectly.
0X00000002 – is an IRQL that was required to access memory – Interrupt Request Level
0x00000000 - is the type of access, where 0 is a read operation and 1 is a write operation
0x804eba3a - The address of the instruction that referenced memory in parameter 1

Stop error 0x0000000A (Stop 0x0A) indicates that there was an attempt in
kernel mode to touch pageable memory at too high a process internal request
level (IRQL). Typically, this error occurs when a driver uses an incorrect memory
address. Other possible causes of this error are an incompatible device driver,
a general hardware problem, and incompatible software


i believe its resetting your BIOS settings that helped, perhaps it reset your HAl settings to Standard PC HAL (Hardware Abstractyion Layer, the bit that is masked by device drivers and shielded from User Space).

its always a good idea to reset your BIOS settings to default (load optimal values) when having such issues.

hope this helps in the future.
