Most performance issues with a laptop are not with the hardware but with the software installed on the computer. Viruses, malware, poorly written programs and poor maintenance practices are just a few things that cause Windows to slow down or even become unresponsive sometimes. When virus scans or registry cleaners cannot help, it is time to start over and restore the laptop to its factory default settings.
1). Connect an external hard drive or USB flash port to the laptop. Back up important data and document files because the recovery utility deletes any user created files when restoring the laptop.
2). Power off the Toshiba laptop and connect the AC power adapter. Press the "0" (zero) key and hold it while pressing the "Power" button on the Toshiba laptop. Wait for the "Toshiba HDD Recovery Utility" menu screen to appear on the display.
3). Press the "1" key to select the "Restore Original Factory Image (Recommended)" option. Click "Yes" when confirmation message appears on the screen.
