If u have a Toshiba Recovery Disc thats what u have to do put it in and refomat ur PC if u dont reformate the drive with a Win XP cd and install a fresh copy of windows
regards hope this helps
If the OP isn't seeing the Toshiba welcome screen, there could be several other issues here, but I doubt it's the fault of the operating system.
It could be (not a complete list):
1.) Incorrect BIOS Settings
2.) Defective RAM
3.) Defective Display
4.) Defective CPU (Less likely, but possible)
5.) Loose Internal Connection (motherboard, display, etc)
etc
etc
I would first try this;
Connect your laptop to a monitor or television via VGA (there should be a port on your laptop). Turn on your TV, boot up your laptop and see if anything appears on the television.. if it does, you have a faulty display, or accompanying component. If it doesn't show anything, try this;
Boot up the laptop and repeatedly press F2. If the BIOS screen pops up, find a setting for " Load Default Settings " or something similar to it, select it, save the changes and reboot.
If that doesn't work, or you weren't able to load the BIOS menu, try this;
Turn off the laptop, unplug it from the power source and remove the battery.
Grab an anti-static wrist wrap and touch a piece of metal to discharge static electricity from your body.
There should be a door on the bottom of your laptop for the RAM and one for your HDD (hard drive).
Locate the one for the RAM (usually it has slots in it to vent the contents. Remove the screw(s) holding the door on and remove the door from the laptop.
You should see 1 or 2 sticks of RAM installed. There will be two metal 'arms', one on each side of the RAM. Carefully push them apart from each other until the RAM pops up.
Remove one stick of RAM by gently pulling up on it (again, be very careful!)
Push the remaining RAM and it's container back in place, where you found it to begin with. Put the RAM door back on, install the battery, plug in the laptop and try to boot it up.
Does it work now? No?! If not, try this;
Remove the battery, plug the laptop from its power source, remove the RAM door again, push those two arms apart, remove the remaining stick of RAM and install the stick you removed earlier (the first stick) in it's place. Close the RAM door, install the battery, plug in the power source and try to boot it up again.
Does it work now? If not, it's most likely not your RAM.. or, it could be that both sticks are bad.. to know for sure you'd have to purchase 1 new stick (new, not used.. we need to know that it works before you install it), remove the old stick(s) of RAM and try the booting up process again.
If none of that helped, you most likely have a bigger problem on your hands.. one that I'm not equipped to deal with at this point, I'm afraid.
I'll check back in a bit to see if my solutions worked for you, and to offer more advice, should I find something in my research tonight to help you
