To better assist you, the members and I would need the exact model number of your laptop/desktop???

Also try this.

Hold down the "D" key, push the power button, release the power button, wait 2-3 seconds and release the "D" key

The laptop should go through an LCD test of solid White, Red, Green, Blue and Black 2 or 3 times.

After completion it should try to automatically boot 2 or 3 times.

Post your results.
