I have a Dell Vostro 15. I was working on a ppt when it suddenly hanged. It has been 3 hours since and it has still not started. I usually keep my laptop on sleep mode with all the background apps working. The screen has turned a light shade of blue and is not responding to any command other than powering down. When it powersu it displays the bluish screen and does not respond to any command. What do I do??
Please list exact Dell model number and version of windows; Example: Dell Vostro 15 5590, windows 10

In the meantime.....
Run Dell eSPA Preboot diagnostic to check the hardware within the system. You could do this by following the steps below.
1, Power off system.
2. Power on system, quickly start tapping F12 key continuously until you see Preparing One Time Boot Menu on right corner of screen. In Dell Preboot menu, select Diagnostic. Report back any error code.

If there's no error code.....
Please power off system and then turn it on and off three times, hopefully it will boot into the Advanced Recovery environment on the third attempt. If successful, select Troubleshoot, Advanced Options, and then System Restore.
