Introduction

Use this solution when there is no image on the monitor (blank screen) after installing a new graphics card, disabling the on-board video or disabling the default graphics adapter.

Solution

If the HP logo screen does not appear, then perform the following steps:

1. Turn on the computer.
2. Press the F1 key when the keyboard light comes on. Wait about 5 seconds.
3. Press the F5 key and press ENTER. This restores the default settings of the BIOS. Wait about 5 seconds.
4. Press the F10 key and then press the ENTER key. This saves and exits the BIOS.

The starting screens should now be visible. Retry several times as necessary. If the monitor stays black, then disconnect the monitor cable to see if any of the monitor's built-in messages appear. If no messages appear, adjust the contrast and brightness up until something is seen. If the picture stays blank, then the monitor may be bad and need replaced.
