Beeps half-dozen times then shuts down.

listen to hear if the cooling fan turns on, you can probably turn it over and look through the grid, if it is loaded with lint then blow it out.. possible your CPU cooling fan is shot

Turn on a working computer with its keyboard plugged in and test if the keyboard is working properly.

If it is, shut down that computer, unplug the keyboard and plug it into the system that is suffering from the missing "NTOSKRNL.EXE" file.

Turn on the system to see if the replaced keyboard resolves the problem.
Press the "F8" key right after the system initializes the boot sequence and before the Windows logo shows up to bring up a menu of boot options.

Choose the "Last Known Good Configuration" option with the arrow keys and press the "Enter" key.
Insert your Microsoft Windows installation disc.

Restart the computer and press the "R" key on your keyboard once you reach the "Microsoft Setup" menu.


Choose the operating system that you wish to repair, type in your admin password when prompted and press the "Enter" key.
Type "bootcfg /rebuild" and press the "Enter" key to rebuild the Windows "boot.ini" file, which may also resolve the issue.

Type "chkdsk /r" and press the "Enter" key to scan the entire hard disk for errors.
Type "exit" and press the "Enter" key to exit the "Recovery Console."

Restart your computer and see if Windows boots properly.

Your computer overheated, it needs a service/clean. With the vacuum cleaner. See my guide to get it working again, it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!

Install more fans, it needs cooler air to get into the chassis.

Take care!

I think its looking for a boot command from the card reader. Which means pressing the DEL or F10 or F2 key repeatedly while booting to get into your bios to change your boot order.

If it wont let you, try booting while pressing the F8 key, with luck it may bring up windows boot options, choose the safe mode. When up, Click on Start - all programmes - accessories - system tools - system restore - choose a date prior to problems. (This is for XP, Vista and Win7 slightly different)

Boot from your windows disk, and choose the repair option.

Or download, UBCD4Win , the ultimate boot cd for windows, This will load a windows shell system with loads of diagnotic and repair tools.

You could download and run Ubuntu without installing, that will give you access to any data files.

If none of this works, the only recourse is to re-install windows. But in
doing this, you will be re-formatting the hard drive which will remove all data on the drive.

If you don't have a copy of windows, you do have Ubuntu. I use it nearly all the time now, even though I have a dual boot system.

did you short the batt. contacts,

it works for me

First, you should be sure that the cooling fans are working properly. Especially the one that is on or directed to the processor. You'll need to open the system up to check this. Turn on the system and make sure all the fans are spinning fast. Now, check for lots of dust or dirt on the fans and processor heat sink. Most likely, the inside of your tower needs to be cleaned. If there is too much dust and dirt in the fans and on the processor heat sink, it can't cool itself and the system shuts down to prevent damage to the processsor once it gets to a certain tempature. I have seen this often. You will need to use a can of air on the fans and processor heat sink. There will be a lot of dust and dirt that will come flying up....which is good Then use a vacuum and a soft bristle attachment to get out the remaining dust. Put the system back together and you should be good.

Your manual should show you how to take the cover off your PC to access the motherboard.

I hope this helps you.

Based on your indication the CD drive is clean, and you know the cables are attached to it, inside the computer. (Flat ribbon IDE interface cable, and 4-pin Molex connector power cable)

1.Go to Device Manager

Left-click on Start. Right-click on My Computer. Go down, and Left-click on Properties. Left-click on the Hardware tab. Go down, and Left-click on Device Manager.

Left-click on the + sign to the left of, DVD/CD-ROM drives.
Right-click right on the name of the CD drive.

(Example: Lite On DVDRW LH-20A1P.
eMachines Support indicates the T5212 has a DVD burner drive, and a CD drive. Right-click on the CD drive name))

In the drop down list, Left-click on Properties.
Left-click on the Driver tab
Go below, and Left-click on the Update Driver 'button'. Now go below, and Left-click on OK.

Close all windows, go back to your desktop screen.
Shut your computer down normally. (Start>Turn Off Computer>Shut Down)

Do Not Restart. We need a 'Hard Shut Down'.
Wait 1 minute, turn your computer on.

Still doesn't work?
Let's play hard ball.

2.Go back to Device Manager. Left-click on the + sign to the left of DVD/CD-ROM drives. Right-click on the name of the CD drive. Left-click on Properties. Left-click on the Driver tab.
This time go down, and Left-click on the Uninstall 'button'. Go below, and Left-click on OK

There will be a Microsoft 'squawk box' that comes up. "Warning you are about to uninstall this device"
Left-click on OK. (It IS okay!)

Close all windows. Shut down your computer normally. (Again, we need a 'Hard Shut Down'. To Restart a computer is known as a 'Soft Shut Down')

Wait 1 minute. Turn your computer on.
After Windows loads all the way, and all of your Start Menu programs have loaded, you should see a pop-up out of your system tray. (Bottom of Windows desktop screen)

"Found New Hardware", and perhaps another one, "Found XYZ CD drive". (XYZ = the CD drive name)

No still?

The driver for your CD drive, is located within the Windows XP operating system on your computer.
If your CD drive does not work now, I suggest it has failed.

Drives such as Optical drives, and Harddrives, are mechanical devices. Their 'Lifespan', is rated in so many hours of usage. Your CD drive may be at the end of it's 'Lifespan'.

I had this problem on my Pavilion DV6000. When I spoke to tech support they told me to unplug my computer and take the battery out for 5 minutes then replace it. I do not know why it worked but it did.
