Hi @bibaclark4,
Are there any devices or media that was connected to it? like thumb drives or SD card / disk? remove those first and check?
try accessing into your Laptop BIOS and check if your hard drive is detected,
if the hard drive is detected, proceed to do a HDD diagnostic test, as I suspect your hard drive might be failing, also it could be due to corrupted OS, what operating system are you using?
Any changes to OS / updates recently?
