Seriously, contact Toshiba Tech Support. Give them the information you put up here. If you need to you can use a PC in the local library, or a friend's PC, to contact them. Or, just call them on the phone.

Have you tried going into Safe Mode?

-a.

It sounds as if you need a new charger. Try removing the battery and start the machine with just the charger. If that works then it may be a new battery you need. Some toshiba notebooks have a 'power saver tool' preinstalled, which is used to monitor battery performance. You can download a copy here:

Not sure if it will be compatible with your machine, but maybe worth a try as it could be a corrupt program causing the problem.

This because you dont have AHCI drivers required for Win XP and you set in BIOS either sata controller or ide controller to an AHCI. You must set to native IDE or anything else like that.
If you wish set an AHCI driver you must press F6 during starting windows XP setup. And put the drivers (get it here) to floppy disk, it will prompted to install required drivers..
Another way to install driver without floppy disk you must inject the driver to windows XP installation CD...

P.S : you cant put the drivers onto floppy, because it wont be read by Windows XP setup..

Would be nice to know error code on the blue screen.That is pointing on the problem-and solution.Anyway, you can try system restore.On boot,computer shows start-up options, and among them is "System Restore".Hit that button and try to restore OS in earlier point of time.Or try Safe mode.Run-msconfig-enter-system restore.To be honest, from my bad experience, blue screen on boot is almost always connected to dying hard drive. Good luck,and keep us posted.

If your model Toshiba laptop has a Restore partition on thehard drive then follow these steps to restore your Toshiba to the Out of theBox condition.
1. Press and hold the 0 (zero) key and at the same time, tap the power buttononce to switch on
your notebook.
2. When the machine Starts beeping; release the 0 key.
3. When prompted by the warning screen; select Yes to continue with the systemrecovery.
4. Select Recovery of Factory Default Software; click Next.
5. Select Recover to out-of-box state. 6. Click Next again.
7. Click Next to Start recovery.
8. Restart the Toshiba laptop when there restoration process finishes running.Follow the prompts that appear on the screen to set up the laptop's date, timeand language settings.

AS YOU ON THE SYSTEM AND EVEN BEFORE WINDOWS STARTS KEEP PRESSING THE F8 KEY CONTINUEOUSLY. A MENU WILL APPEAR. SELECT SAFE MODE AND ENTER. WINDOWS WILL LOAD IN SAFE MODE. THIS WILL SOLVE SOME OF YOUR PROBLEMS. NOW RESTART THE SYSTEM IN NORMAL MODE.

IF THIS DOES NOT WORK SELECT "LOAD WINDOWS WITH LAST KNOWN GOOD CONFIGURATION " AND THEN RESTART. THIS WILL SURELY SORT OUT YOUR PROBLEM.

PLS REPLY OR COMMENT. THANKS

It is a problem with Hardisk & RAM.first you can checked it reinstalled the OS.if problem does not solve then checked it repace the another RAM & hardisk.

Depends. When you say it shuts down, do you mean it flashes blue and then shuts off / restarts, or just plain shuts off, and stays off?
If it is flashing blue real fast, then shutting off, here's what you do:
While starting the computer, press F8 as soon as the brand logo goes away, and keep pressing until you get a screen that says Safe Mode on it. Then highlight the Disable Automatic Shutdown option, and hit enter. Use the computer until you get the blue screen. It will give you an error message, followed by a stop code. (0x0000ce or something like that). Get that error code, and bring it back here. I'll tell you what it means.

If it is simply turning off without warning, and stays off, most likely it is overheating. In which case, head to Wal-Mart, go to the computer section where the keyboards are, and pick up a can of compressed air. Blow out the computer right where you see the vent on the side (maybe on back), and try that. If that doesn't work, get a laptop cooling pad and use that. If it still doesn't work, then the heatsink for the CPU needs to be recompounded, in which case take it to a shop. Unless that is you ABSOLUTELY know what you are doing and can do it yourself. IF YOU HAVE NOT TAKEN A LAPTOP APART BEFORE DO NOT ATTEMPT IT WITHOUT A PROFESSIONAL, YOU WILL BREAK IT.

Let me know how it goes, and i'll try to help you further if need be.
