Computer Problems Part 4 (booting into Win 7 safe mode)

This video immediately follows "Computer Problems Part 3". It begins with the frozen Win7 loading screen. I physically turn the computer off by pressing the power button and then turn it on by pressing the power button. Upon startup, I enter the BIOS to check the PC Health Status (rail voltage, temp). I then exit the BIOS and boot into Win7 Safe Mode with Networking. The system boots successfully and I enter "my computer" to view the display drivers. After checking the drivers, I restart the system.
