Sounds like your hard drive may have failed. You are in what's called a cyclical reboot and I bet there is a BSOD (blue screen of death) hiding in there somewhere. Trying booting into safe mode (Press F8 shortly after powering on) If you have an option to "Disable Restart on Failure" choose that option and hit Return. This will cause it to stop at the BSOD and you can make note of the error message. You may also try reseating the hard drive as well. Most times I have seen this in laptops is for an "unmountable boot volume" or corrupted OS.
Let me know what you find.

Not necessarily. If the drive gets power and the heads aren't crashed (and you would probably hear loud clicking if this were the case or nothing at all) you can pull the drive and probably read it just by connecting it via a special cable to another computer. If the drive is okay, you wouold probably be able to restore your system using recovery disks as well.

The drive is most likely bad and as above replied, that doesn't necessarily mean data is lost. You need to get to a good pc. Connect the bad drive as a slave on the good pc. If you don't know how to do that, there are several websites that explain how. Not too hard. Then you should be able to see the drive. Open it up and if you have any saved files, you can copy them to the good pc. Other than that, you probably need to purchase a new hard drive and re-load windows.
Good Luck

It's not the harddrive. If it were, the BIOS would start and you get display before it stops.
See if you can get into BIOS (unilkely but try and see if you can.) If not, then you have a MoBo issue of some kind. Backup your harddrive using another PC and then take the laptop into a servicing depot.

A) unilkely because if the BIOS cannot read the saved settings in CMOS, it uses preset defaults in the BOIS program. Likely, your MoBo will need replacing. It could be a grounding issue but likely, the MoBo is toast.
B) You remove the hard drive and connect it via PCI or USB to another computer. The computer will detect it as a slave drive and you can see the contents of it. Be sure to set the jumper on the old drive as "slave" or "cable select". Copy you personal files to the new computer's master drive. All PCs have an extra harddrive PCI connector or you can buy a PCI-to-USB connector and connect to the USB port.

My apologies. When I wrote my response I forgot to pick up on the fact that the first hard drive is from a laptop while you are trying to back it up onto a desktop. The connectors are different between laptops and desktops when it comes to hard drives. Both as PCI but the size of the connector head is different (3.5" for desktop, 2.5" for laptops)
You need to get a PCI to USB connector. I have one called EZ-Connect made by Kingwin http://www.kingwin.com Just buy one at the local computer store. The connector will fit both 3.5" and 2.5" PCI sizes.

If it's a laptop, then I would suggest shipping it back to the manufacturer. Is it still under warranty?

My reaction would be that your copy of Windows does not have a USB device driver for that laptop hard drive. Try and see if you can connect the laptop hard drive to the slave SATA connector on the desktop MoBo

same chipset, same problems... nvidia 6150go\6100go.. i can give you an advice: disassembly your laptop, disconnect the heatsink from motherboard. remove thermointerface from the northbridge(6150go or 6100go). the next thing you should to find is soldering station with "blowing foehn" (you'll fit the cheapest one). set the temperature to 150-200 degrees and begin to blow onto the crystall of the northbridge chip. the time to blow is 15-20 seconds. after that, disconnect the CMOS battery, connect the power-on board,lid-sensor,memory modules and turn on the laptop. the laptop will succesfully turns on and will show you a picture with 90% probability. and what's the point? with this action, we have discovered the failure of the northbridge chip 
lamo, I'm quite sure that you are correct in your expertise
But you have revived about 6 old threads in less than an hour
And this one is working anyway
And your advice seems too technical for the average user to do.
Please do not revive old threads, especially when they are solved!
Julio is presently looking into stopping this from happening (on much older 18month old threads)
