Remove the hard disk and try to boot in the BIOS. If you can't then you have a hardware fault - most likely the motherboard has failed. Try to find a replacement and put it in. OR Is a windows file corrupt, driver for a device or device itself.
Try removing some of the devices like the CD-Rom, the wireless card, one of the memory sticks - all this stuff is usually accessable through covers on the bottom of the laptop. Then reboot each time until problem is resolved and boots fine - replace defective unit but normally is a software problem, or on older machines a corrupt hard-drive. Try reinstalling windows as a last resort. Here are some recovery tips:

Upon start-up hit F1 (or other key to get to CMOS or SetUp Menu) If there is a pass-word on the CMOS - turn power off, remove battery and find the CMOS battery (sometimes is in a package with a red and black wire with 2-prong clip) usually its a silver battery about the size of a nickel - remove this battery and short out the two terminals for a few seconds - this resets the CMOS to factory and removes any pass-word on CMOS only Not on Windows - Special software is necessary to remove passwords from Windows operating System.

Have the CMOS Start-Up or Boot-Sequence, start on CD-Rom and place XP (or OS you are using) in CD/DVD drive and reboot. You may have to find that option in the CMOS menu or SetUp menu - you may have to change the boot-order from HD (Hard Drive) to CD-Rom.
Reboot and tap F12 to bring the boot menu up, to boot from CD.

At this time you can try to recover windows with the R selection instead of a new installation which will have you replacing all the drivers for all hard-ware including motherboard and ethernet cards. Everyone should have a drivers disk made for their computer so that this problem can be fixed easily.
Also is good to have a copy of your operating system with the Product Key (25 digit code for XP or whatever OS you are using) Sometimes product key is on the bottom of the computer.
If you dont know your product key you can down-load software to retrieve this info for you so that you have your key on hand prior to any reinstallation of your OS.
If you can't repair you must reinstall your OS. You may be able to have two operating systems installed on your computer so that you don't erase all your drivers and have the new operating system find these drivers before eliminating the other Windows Folder - be careful as some Registry editing may be necessary for windows not to find the second OS or will give you the option of which OS to boot to on Start-up of Windows.
Please post your feedback and Vote if the problem resolved as per your satisfaction.

The 3 LED's (Num Lock, Caps Lock, Scroll Lock) are used by Dell to diagnose no-post issues such as yours. The only error code close to yours is [Num Lock ON, Caps Lock FLASHING, Scroll Lock ON]. This indicates a a memory error. Try reseating the memory modules. If you have 2 memory modules, insert one at a time to determine the faulty module.
