Windows 7 Desktop Stays Black | How To Fix

Why is my screen black when I start Windows 7: Video adapter problems are the most common cause of this issue. First, try to find out if there's a problem with the cables you're using or the way they're connected. If you have an alternate way of connecting your monitor to your PC, try it. For example, if your monitor is connected using an HDMI connector, try disconnecting it and then connecting with a DVI or VGA connector instead.

Always turn off the power to your computer and all external video devices before plugging them in or unplugging them.

If you're using multiple monitors, try using just a single monitor. If this solves the problem but you're not using the cabling options you ultimately want, attach the cables back to the way you want them, remove all floppy disks, CDs, and DVDs from your computer, and then try the following troubleshooting procedures, in order. If the steps in the first procedure don't fix the problem, move on to the next procedure.

Use the "Enable low-resolution video (640×480)" startup option, and then update your video adapter driver
  • 1. Click the Start button Picture of the Start button, click the arrow next to Shut Down, and then click Restart.
  • 2. Do one of the following:
    • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You must press F8 before the Windows logo appears. If the Windows logo appears, try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
    • If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
  1. 3. On the Advanced Boot Options screen, use the arrow keys to highlight Enable low-resolution video (640×480), and then press Enter.
  2. 4. Log on to your computer with a user account that has administrator rights.
If you can see your desktop, there's a problem with your video adapter. Try updating your video adapter driver. For more information, see Update a driver for hardware that isn't working properly.

If these steps solve the problem, you're done. If not, go to the next set of steps.
