First step you need to do is once unit is powered on keep tapping the F10 key check now the display works on this screen if it is fine then issue would be software.
Second step try doing a system restore to the date where unit was working fine.
Third step please visit HP Website and update the Bios, Graphic & Chipset driver and have it check.
Please note incase unit display is fuzzy in Bios you need to call HP Technical support check the warranty and get the screen replaced.
