A ticking sound is usually a major indicator that your Hard Drive is / has gone out. I would look at replacing your Hard Drive. If it is a bad Hard Drive it would lock your system up bad enough to have to remove the battery to shut down the system.
If this is the first time your trying to start up this computer try to restart it. Sometimes brand new laptops can fail to find the operating system on first startup. If this isn't the case it sounds like your Hard Drive is either disconnected or has had a critical failure.
How Do I Change the Primary Master HDD User Password?
Prior to loading an operating system, your computer will first execute the BIOS program. The BIOS has an extra password feature, called the hard disk drive (HDD) user password, that can't be bypassed and provides a layer of defense to keep your data secure. To change an existing HDD user password you will have to load the BIOS menu, which is only accessible during the computer's operating system reboot procedure.
1. Close any windows that are currently open on your computer. Eject any discs inserted into the optical drive and disconnect any peripheral USB devices.
2. Open the "Start" menu and select "Shut Down." Turn on your computer once the operating system finishes shutting down.
3. Press the key your computer uses to load the BIOS menu. For example, with Dell computers tap "F2" when the "Press F2 for Setup" option appears. Press the "Access IBM" key on IBM laptops or "F10" on HP desktops.
4. Navigate to the BIOS tab that contains the HDD password option, which will usually be the "Security" tab. Some computer manufactures instead include the password option in the "Advanced" tab.
5. Scroll down to the option labeled either "User Password" or "BIOS lock" and hit "Enter." Type the current master HDD user password when the prompt appears and press "Enter."
6. Input a new HDD user password and hit "Enter" again. Navigate to the BIOS tab labeled "Exit" or something similar.
7. Move over to the "Save and Exit" entry and press "Enter." Select "Yes" and tap "Enter."
Sounds like your hard drive died. If hard drive is dead you wont be able to get into anything but the bios. Hold down the CTRL key when computer starts and dont let go and try to force it into going into bios for you.
Shut down the computer.Disconnect the ide cable from hdd .Just connect using primary hdd and boot the computer. Shut down the computer. Connect the secondary hdd both IDE and power cable. Restart the system and go to bios . Check if the both hdd are detected in bios. If detected boot to desktop. If not detected reset bios settings to default.Restart computer and check. IF still not detected shutdown computer.Disconnected secondary hdd and primary hdd,connected secondary hdd to primary ide connecter and check in bios. If still not detected try connecting secondard hdd on different computer and check.
Try taking out the hard drive and putting it in an external hard drive enclosure to see if the hard drive and operating system is ok. If you can not access the hard drive then you should try installing a new hard drive and operating system.
How old is the laptop and is it sued a lot. Is it left running 24 hours a day.
Hard drives fail all of the time and it sounds like yours died.
have u tried start.in the find type msconfig go to startup and remove all ticks. general set to selective startup and apply then ok. as it sounds as a virus checker is still working in the back ground.
take to dell and demand the hdd be replaced with a new PE windows xp installation.
if they refuse to do this, consult legal advice as the problem is caused by dell and microsoft transfering and manipulating data between the os and the bios via the ntfs file system (recovery) and the hal.dll file.
problem exists because: ntfs file system can manipulate data sent and recovered to the bios, if for instance your dell laptop etc shut down due to low battery then the bios data and the os data would be out of sync, therfore the operating system would render the previous sector that held the data on the hdd as a 'bad' sector and would then use another 'good' sector to transfer data between os and bios at startup and shut down.
as soon as all good sectors have been used, the bios and the operating system will be out of sync and the hal.dll file or the ntfs file system would not allow the operating system to boot because of the data lapse.
demand a new hdd from dell with their OEM PE windows xp installed, if they refuse, then sew them for damaging your hdd by using a virus type file system (virus is how it works, so in release notes on most websites refer to this) which corrupted your hdd's life expectancy.
chalenge microsoft and dell to refute your alegation in court, after all your claim will make them want to settle out of court instantly...
good luck, and don't be afraid of the challenge against microsoft or dell, as a consumer you have rights and your rights are what is at the interest of the law........
Operating system not found indicates that the system is not seeing a bootable device. Possible causes are:
1. Hard drive not detected due to loose connection. Reseat the HDD.
2. Hard Drive is failing/Failed. Replace HDD
3. System has a floppy drive and a diskette in the drive, remove diskette, reboot
4. Hard drive not in boot sequence. Reset BIOS to defaults
