incorrect shutdown with low battery will always cause problems....
first of all youre gonna have to put some charge into the battery...
then..press the power button to startup and wait for activity...lights , sounds etc..then press and hold power button until you hear pc shutdown.then restart...you may have to choose startup in option screen like start with last good config etc but now it will be back on.

Sounds like you may have too many things opening on startup. How much ram is in your pc?

you need to perform a repair of operating system using windows cd which came along with the system
log on to microsoft's website and get info how to perform a repair.

HP Notebook PCs - "Windows Unsafe or Sudden Shutdown" Blue Screen Error Occurs During Startup or Boot

Description
Windows XP may not start and the following error message may appear on a blue screen:
Windows Unsafe or Sudden Shutdown
This error occurs after Windows was not shutdown using a safe method. The notebook may have been turned off without clicking Shut Down or briefly pressing the computers Power button. The power may have been suddenly disconnected from the computer or the Power button may have been held for more than 5 seconds.
An unsafe shutdown can damage some of the Windows system files, preventing the computer from starting properly.
Solution
If the error occurs allow the operating system to complete a check of the hard disk. Windows will prompt your to run CHKDSK. CHKDSK scans the hard drive for damaged files and repairs the files if necessary. The scan may take up to an hour depending on the size of the hard drive and the number of damaged files. The computer will restart when the scan is complete and Windows should start normally.
If Windows will not start or the computer will not boot after the scan is complete see: HP Notebook PCs - Troubleshooting a Startup or No Boot Problem (In English)

you was probably installing updates in the background and youve interrupted install and shutdown improperly (reason)
turn on pc and press f 8. if youve never done this before;as soon as you see anything at startup keep pressing f 8 youll still get to the place you want to be.select start up using last known good configuration.
