There are several possibilities within two categories:
SOFTWARE (you are using MS, so this is more likely)
HARDWARE these symptoms can be caused by bad battery and/or bad PSU (AC Power Supply Unit)
Software: You may have a virus, or may have damaged the NT kernel, or some critical software components by installing cheap games or bad SW. Read the recovery instructions on your XP CD to boot and run recovery and/or utilities that might repair the laptop OS. If you have no CD, try booting and hitting F6 key after BIOS screen... then explore the options there. Next, try booting and hitting F8 key after BIOS screen... then explore the options there.
If there are no problems repaired or evident in software, you should remove the battery, plug in the PSU and try booting. If all goes well, your battery is probably bad. If NOTHING happens, then your PSU is definitely bad (or the PSU cable/jack/connection to your computer is bad)
Conversely, remove the PSU and boot only with the battery. If it boots up (or goes farther than it did before) then the battery may be low/damaged BECAUSE the PSU is bad. If your laptop does not even open/get at least to BIOS screen, then the battery is dead. Try recharging overnight with laptop off but plugged into AC. If it is the same in the morning, replace the battery.
Both the battery and PSU can be checked with a VTVM, to compare voltage/output levels, with the ratings on the labels
