Unplug A/C/ power and battery, hold power button down 30 seconds to drain residual power.

Replace battey and A/C power, try powering up.

If it still wont boot, tap the F8 key to access System Recovery Options to try to System Restore working backward as far as necessary.

If this fails, everything possible is here for Troubleshooting Windows 7 Failure to Start leading up to if necessary rescuiing your files to run Toshiba factory recovery (google how it is done for your model) or doing the superior Clean Reinstall Windows 7

To access the recovery partition do the following:
Power off the laptop.
Hold down the 0 (zero) key and turn the laptop on. Keep holding down the zero key until the TOSHIBA logo appears.
Start tapping the zero key repeatedly at this point.
Stop if the unit beeps or when the TOSHIBA logo disappears.
The screen should flash HDD RECOVERY MODE for a second and then it will load the Toshiba recovery program right from the hard drive.
Note that this erases all data, and reloads all factory default software.
